Basic Statistics for Business and Economics Essay Example for Free

Basic Statistics for Business and Economics Essay Over the last four weeks of being in the QNT/351 course our team has learned a lot about researching a hypothesis and understanding the mean. The hypothesis testing begins with the statement and the assumption that determines the population of the mean, (Lind, 2011, p.288.). There are five steps taken which include; state the hypothesis, select level of significance for it, identify the test statistics, formulate decision rule, and take a sample to arrive at a decision. On the contrary, however, McClave, 2011 states that there are seven steps including; null hypothesis, alternate hypothesis, test statistic, rejection region, assumptions, experiment and calculation of test statistic, and the conclusion. With setting a hypothesis and testing it is important to understand the mean and how to compare it amongst two or more groups. With testing the mean with multiple groups, the data collected is used to help determine the probability of a given amongst two distinct groups being analyzed which have the same or equal variances. This info it all based off the given hypothesis and should result in proving the null hypothesis stated. When looking at the mean the distance noted between the hypothesis and the mean placed is a value given as a result of the probability of occurrence. When analyzing and testing the means of the two groups we use the variance analysis. An example of this type would be testing the means of the two groups based off statistical models and valid conclusions. Along with completing the testing of the means of the groups, we must also calculate the variance according to the distribution of the differences in means. If the standard deviation is known we can calculate the z-score by using the difference of the variance and the mean. In calculating the correlation between the two variables we see that it is crucial to know the characteristics of the coefficient. According to Lind, 2011 pages 386-389 we can calculate the coefficient of correlation. The coefficient of correlation can help dete rmine the cause as well as effect amongst the two variables. Calculating these numbers is  crucial as the results give information which help determine the level of significance of the given hypothesis. References Lind, D. A., Marchal, W. G., Wathen, S. A.

Student Athletes Should Not Receive Additional Money Essay -- Argument

Student Athletes Should Not Receive Additional Money When a student athlete signs a letter of intent to play at a division one school, he or she is generally happy for the opportunity to perform at the highest level of college competition. Like all good things though, they eventually come to an end. After awhile athletes soon begin to realize not all of their expenses are paid for. Because some of the extra costs in college are put on student athletes, some suggest the NCAA and other sources should provide additional funding to help athletes out. This issue has created a heated debate over the relationship between money and college athletes. On the contrary, the stronger argument lies with those individuals that say student athletes should not receive additional money, and how the NCAA is dealing with the situation right now is fine. In other words, athletes competing at the division one level do not need to be paid any amount of money on top of obtaining a scholarship. If the current law the NCAA has now is working, then i t should not be fixed. Because this is such a huge topic, there are still arguments for the opposition. In contrast to the NCAA’s rules and regulations, those in favor of paying student athletes say money is a necessity to get through college. They say even though full ride athletes receive a free education, certain accessories still require money from their own pocket. Some of these items include laundry, clothing, phone bills, transportation, entertainment, toiletries, and eating off campus. The money for these things usually comes from parents or, if they are lucky, a grant of some kind is given to the athlete. But in order to receive a grant, a student athlete must apply for financial ... ...regarding college athletes receiving money many things would be different in the future. A major concern involves recruiting. Universities allowed to pay players would be able to buy recruits and this may persuade them to attend the school offering the most money. It’s almost like a free agent in professional sports. Attending the school with the most to offer decreases the likelihood of a fair playing ground for all of college athletics. As a result certain schools would be major powerhouses and it would stay this way forever. Concluding all the ideas and argument above illustrates just a small portion of why the NCAA has yet to pass a law of this magnitude. The evidence for all those in supporting athletes receiving money are not strong enough for action to take place. Overall if student athletes begin to get paid, collegiate sports will become corrupted.

Access to Education

For My Research paper, I would like to talk about Access to Education in world countries. This subject is important to me because I want to become a teacher someday.For most Americans, we usually have the typical ordinary lives, we go to school, get a job and work. Now-a-days most Americans, don't go to school but imagine not being able to go to school your whole life and just working from the age of 7. Now that's something to think about, for many world countries, it`s not easy to get access to education like it is for the people in America. For third world countries they don't get educated period, and we American are forced to go to school by the age of 16, we take it for granted. Could you imagine not going to school and getting an education? How would you feel if you didn't have supplies for class or a classroom to go to? These are just some questions to think about. Education is one of the most difficult things to get in third world countries because of lack of funding, un-trained teachers and also no classroom. Body 1 Education is one of the most difficult things to get in world countries because of lack of funding. According to https://www.globalcitizen.org/en/content/10-barriers-to-education-around-the-world-2/ one of the number one reason to having education in world countries is â€Å"a lack of funding for education†, from this article it says † the amount of total aid that's allocated to education has decreased in each of the past six years and education aid is 4% lower than it was in 2009.† Wow, the fact that education has decreased since 2009 is not a good sign, we should be going up higher but even in the united states there are children not wanting to go to school, they feel being a basketball player or singer is better.

The Story Cinderella Through a Marxist’s Eye

In a Marxist view, a capitalistic society equates economic status to social status. The story of Cinderella by Charles Perrault highlights a number of these views. Cinderella’s stepfamily longingly desired to keep their social standing. They are willing to but Cinderella into poverty by making her their slave. By doing so, they ensure their social and economic standing. The prince has a similar need to keep his high-class standing but requires a bride to maintain these necessities. The prince reaches his goal by marrying Cinderella to create a possible heir to his throne. Cinderella’s stepfamily and the prince sustain their economic power by upholding their social status. In a capitalistic society, there is a dependency on having a lower class in order to maintain the higher class. Since Cinderella’s stepfamily has a lot of money and she has nothing, they maintain their economic status by demoting her to slavery. In the beginning of the fairy tale after her mother dies, her father remarries to maintain his economic status. Cinderella is unfortunate when soon after his death she is plunged into poverty. Throughout the story, her stepfamily continues to live in luxury while keeping Cinderella in squalor. While her stepsisters slept in expensive beds and were dressed in lavish fashions, Cinderella had to sleep in a bed made of straw and wear old dirty rags. The stepmother requires Cinderella to be kept in poverty in order to maintain their economic and social status. Cinderella will never have the chance to rise to the higher class since she does not earn any money. Unless someone existing in the higher class takes her out of her poverty, she will continue to exist within the lower class. In this time period, people were defined within society by how much money they acquired. The prince’s social standing of being in the ruling class is also dependent on economic wealth. In order for his family to stay in power he needs to have an heir to the throne. He hosts an extravagant ball at his castle to find a suitable bride and all the ladies in the town were invited to attend. Cinderella wanted eagerly to go the ball, but knew she was not wealthy enough to look the part. Cinderella is fortunate enough to have help from a supernatural force, called her fairy godmother, to transform her into appearing like she was from the high-class society. Her beauty was so intriguing that the prince fell in love the moment he looked at her. Once he finds Cinderella from the help of his servants, she is pulled out of slavery and into the ruling class. The prince enables his family to maintain their economic and social status by marrying Cinderella. He now will have an heir to the throne and his family will be preserved in the royal society. The struggle between the higher and lower classes of society is prominent within Marxism. Charles Perrault highlights this ideology in the fairytale of Cinderella. Cinderella’s stepfamily wants to keep their maintain their economic and social standing. They make Cinderella their slave and instantly plunge her into poverty. Their economic standing is ensured as soon as she is put the lower class. The prince similarly keeps his social standing when he finds a bride. The prince and Cinderella get married therefore maintain his economic and social status and ultimately creating a possible heir to his throne. In the story Cinderella economic status is ensured through differences in social statuses. Marxist views uphold this society and therefore capitalism is sustained.

Otto Bayer and the History of Polyurethane

Otto Bayer and the History of Polyurethane Polyurethane is an organic polymer  composed of  organic  units joined by  carbamate (urethane) links. While most polyurethanes are  thermosetting polymers  that do not melt when heated,  thermoplastic polyurethanes  are also available. According to the Alliance of The Polyurethane Industry,  Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethanes are best known to the public in the form of flexible foams: upholstery, mattresses,  earplugs, chemical-resistant coatings, specialty adhesives and  sealants, and packaging. It also comes to the rigid forms of insulation for buildings, water heaters, refrigerated transport, and commercial and residential refrigeration. Polyurethane products often are simply called â€Å"urethanes†, but should not be confused with  ethyl carbamate, which is also called urethane. Polyurethanes neither contain nor are produced from ethyl carbamate. Otto Bayer Otto Bayer and co-workers at IG Farben  in Leverkusen, Germany,  discovered and patented the chemistry of polyurethanes in 1937.  Bayer (1902 - 1982) developed the novel polyisocyanate-polyaddition process. The basic idea which he documents from March 26, 1937, relates to spinnable products made of hexane-1,6-diisocyanate (HDI) and hexa-1,6-diamine (HDA). Publication of German Patent DRP 728981 on November 13, 1937: A process for the production of polyurethanes and polyureas. The team of inventors consisted of  Otto Bayer, Werner Siefken, Heinrich Rinke, L. Orthner and H. Schild. Heinrich Rinke   Octamethylene diisocyanate and butanediol-1,4 are the units of a polymer produced by Heinrich Rinke. He called this area of polymers polyurethanes, a name which was soon to become known worldwide for an extremely versatile class of materials.   Right from the start, trade names were given to polyurethane products. Igamid ® for plastics materials, Perlon ® for fibers.   William Hanford  and  Donald Holmes   William Edward Hanford and Donald Fletcher Holmes invented a process for making the multipurpose material polyurethane. Other Uses In 1969, Bayer exhibited an all-plastic car in  Dà ¼sseldorf, Germany. Parts of this car, including the body panels, were made using a new process called  reaction injection molding  (RIM), in which the reactants were mixed and then injected into a mold. The addition of fillers produced reinforced RIM (RRIM), which provided improvements in  flexural modulus  (stiffness), reduction in coefficient of thermal expansion  and better thermal stability. By using this technology, the first plastic-body automobile was introduced in the United States in 1983. It was called the  Pontiac Fiero. Further increases in stiffness were obtained by incorporating pre-placed glass mats into the RIM mold cavity, called resin injection molding, or structural RIM. Polyurethane foam (including foam rubber) is sometimes made using small amounts of  blowing agents  to give less dense foam, better cushioning/energy absorption or thermal insulation. In the early 1990s, because of their impact on  ozone depletion, the  Montreal Protocol  restricted the use of many  chlorine-containing blowing agents. By the late 1990s, blowing agents such as  carbon dioxide and pentane were widely used in North America and the EU.

Blaxploitation Essay Research Paper The Emergence of

Blaxploitation Essay, Research Paper The Emergence of ColourIn today? s culturally diverse, politically right society, it is difficult to believe that at one clip racism was non merely accepted as the norm, but enjoyed for its amusement value. Persons of African descent in North America today take the big, diverse pool of chances offered by the movie industry for granted. Much like Canadian theatre nevertheless, there was a clip when a black adult male in any function, be it servant or break ones back, was virtually unheard of. It took the blaxpliotation movies of the early 19 1970ss to alter the stereotyped word picture of Black people in American Cinema, as it took The Farm Story, performed by a little troop of Canadian histrions, to make a Canadian theater industry. To be more specific, it took the release of Melvin Van Peebles, Sweet Sweetback? s Baadasssss Song, in 1971, to alter the tradition position of Black people in American movie. ? Porter? s Tom was the first in a long line of socially acceptable Good Negro characters. Always as Toms are chased, harassed, hounded, flogged, enslaved, and insulted, they keep the religion, n? er bend against their massas, and remain hearty, submissive, stoic, generous, selfless, and oh-so-very kind. ? ( Bogle,4 ) The early soundless period of film introduced five basic originals for Black characters: the Tom, the Coon, the Tragic Mulatto, the Mammy, and eventually, the Brutal Black Buck. America? s foremost Black character found manifestation as the aforesaid Uncle Tom in Edwin S. Porter? s, Uncle Tom? s Cabin, which was released in 1903. ? The paradox was that in actuality Tom wasn? t Black at all. Alternatively he was portrayed by a nameless, somewhat fleshy histrion made up in blackface. ? ( Boggle, 4 ) This was a common pattern developed by the theatre, and carried over, as were many of the moving techniques, to silent movie. Tom? s presence, and the visual aspect of the fou r Black originals which were to follow, served the same intent: ? to entertain by emphasizing negro inferiority. ? ( Boggle, 4 ) Although holding no positive consequence on the position of Black people in America socially, the tom character opened the door for Black histrions in film. Sam Lucas became the first black adult male to be cast in a prima function as a Tom, and in 1927, Universal Pictures signed James B. Lowe, a fine-looking black histrion, for the lead function in the Universal Pictures production of Uncle Tom? s Cabin. Lowe was chosen to play the portion because movie manager Harry Pollard, a former blackface histrion, believed he? tantrum in with the realistic demands of the times? ( Bogle, 6 ) Tom was to be followed by the coon, although he remained the cinematic Black character favourite. Where Tom was an adorable character, the coon provided audiences an object of amusement. Two discrepancies of the coon shortly emerged: the piccaninny and the uncle ramus. ( Bogle, 7 ) The Pickanny was the first coon type to look in film. ? By and large, he was a harmless, small crazy creative activity whose eyes popped, whose hair stood on terminal with the least exhilaration, and whose jokes were pleasant and diverting. ? ( Bogle, 7 ) The Pickaninny provided audiences with an amusive recreation, and shortly found his manner into the Black Marias of the mass audience. Following to debut was the pure coon, ? a good-for-nothing nigga? , whose undependable, brainsick, lazy nature was good for nil but feeding and doing problem. This character found its pinnacle of success in Rastus, a good-for-naught Black featured in a series of movies released between 1910 and 1911. The concluding coon brother would emerge as the tidal bore to delight metaphoric cousin to the Tom. Quaint, and na? ve, the Uncle Ramus character distinguished himself through his amusing philosophizing. ( Bogle,8 ) In general, the cinematic coon was used to bespeak the Black adult male? s contentment with his submissive place in society. Besides emerging around this clip period is the tragic mulatto: a negro visible radiation plenty to go through for white, who must contend against the negro contamination to either rise above his coloring material, or autumn victim to it. Mammy, a character closely related to the amusing coon, was the following to emerge. Headstrong and copiously female, Mammy debuted around 1914. The Mammy function would be perfected by Hattie McDaniel in the 1930? s. From the mammy functions emerged the Aunt Jemima, a male or female character who had a spot more tact and were, for the most portion, Sweet and congenial. The concluding original emerged in D.W. Griffith? s The Birth of a Nation ( 1915 ) . Picturing life before and after the civil war, all four originals are present in this movie. It depicts recreant Blacks who overpowe r the charitable, white Southerners and leave on a way of lechery, coarseness and offense. The ultimate end of these wild beast-men is sexual laterality of the pure, guiltless white adult females. At the movies decision, the white work forces of the? unseeable imperium? drive in to salvage the twenty-four hours and reconstruct white domination in the South. Proudly know aparting, D. W. Griffith, touted as one of the fore-fathers of film, uses his movie command to demo audiences what happens when? slaves get overweening? . The five originals would govern in black film for the following 50 old ages. Although Black movies did emerge, it was for the most portion produced by white production companies for a black audiences. Black Independent production companies such as the Ebony Motion Picture Company began to emerge in the 20? s, but the stereotypes and capable affair stayed the same. A common subject of societal mounting, the ultimate end of the Black being suburban life, ruling Black theaters. ( Cham, 20 ) Throughout the 30? s and 40? s the mobster movies rose to the bow, normally picturing gun-totting, slick-talking Blacks, entent on doing it large. Despite the presence of Black independent film makers such as George Randall, African American issues were basically ignored. The 50? s and 60? s brought societal agitation and the Civil Rights Movement brought a demand for movies with a stronger message. The originals of the 20? s and mid-thirtiess were no longer acceptable, and the few Hollywood? race movies? ( which normally starred Sidney Poitier ) , were no longer adequate. ? Hollywood was still unable to spot or picture the full spectrum of Black American life and culture. ? ( Cham, 21 ) In 1971, Black movie experienced an epiphany. It came in the signifier of a low-budget, severely made Gallic movie by the name of Sweet Sweetback? s Baadasssss Song. It was created about wholly by one Black man- Melvin Van Peebles. This marked a extremist alteration in Black film. ? In 1971, Melvin new wave Peebles dropped a bomb. Sweet Sweetback? s Baadasssss Song was non polite. It raged, it screamed, it provoked. It? s echos were felt throughout the state. In the Black community it was both hailed and denounced for it? s sexual rawness, its butch hero, and its word picture of the community as downpressed and in demand of rescue. ? ( Diawara, 118 ) Van Peebles movie sparked an detonation of what would go known as blaxploitation movies. What Sweet Sweetback Baadassss Song did was interpret Black Stereotypes otherwise. He, and other Black managers of the clip, took the Black Buck, Coon, and Mammy stereotypes of the epoch before and modernized them. ? Mammy? lost weight and grew an Afro, going the ultra-stylish prima donna which was personified best by actress Pam Grier. The Black Buck emerged dominant, ready to contend his historical oppressors. Blaxploitation movies acted as a cleaning procedure, through which black movies were finally able to accurately picture the African American experience. Directors such as Spike Lee and Jon Singleton were able to make? race movies? which confronted the serious urban issues of the clip, without utilizing old stereotypes. It is of import to observe, nevertheless, that Sweet Sweetback is non considered a blaxpoitation movie, as it is excessively artistic to be considered such. Rather, Melvin Van Peebles foremost movie was the accelerator for the cleaning blast. ? The Farm narrative? marked a point in time- before it there was no Canadian individuality in theater, after it there was. In the same manner, Melvin Van Peebles? film marked the minute when African Americans reclaimed their individuality. They were no longer content with the cinematic functions offered to them, and so they began to make their ain. Although blaxploitation movies were subsequently commercialized, their purpose and consequence stayed consistent, and have created the ethno-conscious film industry we find today. Bogle, Donald.

Homework - Assignment Example Instead of acknowledging him as a treasure for his long service to the industry, his organizations hired a younger and more capable worker to oversee and assess his work (Schlossberg 57). He probably felt greatly unappreciated after all he had done for the company. Hank should first have taken time for a lengthy period of reflection in which to consider his options before returning to work. He might have asked for a few days for this. During this time, he could have confided in a counselor about his concerns and worries in the workplace. He could also have confided in support groups for elderly workers who are confronted by changes in the workplace that could very well portend their dismissal if they are unable to keep up with the changes. Elaine could have been more compassionate and given Hank more time to adapt to the changes in the workplace. She, as well as the other executives could also have started a support group as well as a training group specifically aimed at elderly workers such as Hank who were confounded by the new expectations that made them appear obsolete. No. I would have pleaded for more time to learn about the new methods of operation that were necessary to succeed in the changing market. I would openly have sought the help of other more productive workers in reaching the numbers of accounts that the company
