Degrees of freedom

This refers to a positive whole number that indicates the lack of restrictions in calculations. The following states below: (rows-1)(columns-1) = (4-1)(5-1)= 3= 12 Critical Value: In hypothesis testing, the critical value is a number that separates a region where the null hypothesis will not be rejected from a region where it will be rejected. It is achieved at a particular percentile range and is then determined using a chart, known as the distribution topic.” The equation below states the critical value at 5% significance level: C.95 =21.026 * The .95 is taken from 100%-5%=95% *The 12 is from the degrees of freedom Lastly, I found what conclusion could be drawn regarding the grades achieved on a semester basis and the time spent on a daily basis on social media sites. I used information from stating my null and alternative hypothesis to either accept/reject my null/alternative. I did this through comparing my critical value at 5% and my chi-squared . My outcome is stated below: cal < co (df) = accept the Ho cal > co (df) = reject Ho and accept HI = 54.33 C.95 =21.026…

The McDonald's Misconception “Caution: Contents Hot.” This warning is everywhere. It’s on a waffle maker, a bowl of soup, on a McDonald’s coffee. The origin of this label is fairly widely known, some old lady spilled her coffee and sued McDonald’s for a bunch of money. But is that the whole story? Not quite. Yes, a woman did spill her coffee, but that coffee was given to her at a temperature between 180 and 190 degrees fahrenheit (McDonald’s). When a liquid is that hot, it “causes third-degree…

February of 1992, 79-year-old Stella Liebeck of Albuquerque, New Mexico, was a passenger in her grandson’s car when she was severely burned by the McDonalds Coffee she ordered through a McDonalds drive-thru. When Liebeck received her order, her grandson who was the driver, pulled his car forward and stopped, allowing his grandmother to add sugar and cream to her coffee. While parked, Liebeck put the cup of coffee between her knees and attempted to remove the plastic lid from the Styrofoam cup,…

There was sufficient statistical evidence at the 5% significance level (t=-3.981 and tcrit=-2.021) to reject the null hypothesis that the mean of D3 is not significantly different than the mean of D1. Consequently, another two-sample Pooled t test was used to test the hypothesis that the mean delivery speed of deliveryman 4 (D4) is not significantly different from mean delivery speed of deliveryman 1 (D1) at a 5% level of significance and 39 degrees of freedom. There was sufficient statistical…

Paradox of freedom Freedom is the power or right that enables someone to act, speak or think according to personal interest without hindrance or experiencing resistance. In connection to the freedom, it requires to be controlled whereby having freedom does not automatically prove one if free. Freedom is also associated and connected to some level of fundamental obligations. It requires one to use freedom wisely as it comes with responsibilities. The paradox of freedom is the essence of…

Basically right in the middle, only to the left -0.13. I am a little below the middle of the authoritarian/libertarian line. More on the libertarian side, at -2.41. I would agree with my results. I believe in the freedom of Libertarians. The idea of economic freedom, political freedom, and freedom of choice. I can also see how I am close to the Authoritarian side, because people do need rules and regulations. There has to be someone or something in charge. People need to be held…

Seeking a higher education in the United States is crucial, especially if one plans to have a stable lifestyle—both in their personal and professional life. However, within the last twenty years, women have dominated the world of academics, and the male dropout rates have decreased tremendously. Does the United States benefit from having uneducated male students? Why are male students dropping out of school? Why are female students succeeding in the world of academics? Will female students…

Cuba is one of very few countries that still maintains a high level of totalitarianism, in today's modern aspects. After the collapse of communism and the Soviet Union the Castro brothers continue to emphasizes anti-Americanism, intentionalism, and support for Marxist-Leninist ideology in Cuba and abroad. Cuba maintains a harsh control over its citizens by doing arbitrary imprisonments, educational manipulation, and religious restrictions. Cuba also, limits human rights: freedom of expression,…

temperature (18°C) and the warm temperature (28°C) compared to the hot temperature (30°C) are almost identical in results, however, the variation of two degrees is still able to establish an impact. When the water temperature rises higher than the control temperature the respiration rate increase but when the water temperature drops below the control temperature the respiration rate decreases. Additionally, we observe in Figure 1, the critical t- value shows the difference of means between…

advantage of a fine motor skill if it is first acquired using the proximal muscles. It is known that the cortical motor representations of the shoulder and elbow muscles are smaller than the hand muscles [12]. Fewer muscles in the proximal motor apparatus allow fewer degrees of freedom compared to the many degrees of freedom in the hand motor apparatus. When learning a new skill with the fine motor apparatus more muscles are used to manipulate an object, and requiring the brain to learn the…
