writers believe that the distribution of income among all residents in the United States is at its worst. The writers in this unit are aware of the unfair income distribution in United States therefore, these writers would support the raise of taxes on the wealthy. Throughout his essay “We are the 99.9 percent”, Paul Krugman uses politics and statistics to support his argument that the 0.01% should be paying more tax.

One Sample T-Test: As proven by the one sample t-test (Figure 1) where the true mean of the difference of history chapter pages read is the unknown variable, there is significant statistical evidence at the standard 0.05 alpha value that listening to music while reading or studying increases scope of study. Because the t-value is positive, it is reasonable to note that listening to one’s favored music has a positive impact on reading larger quantities. 95% of all samples of differences in pages…

The two-sample t procedure is appropriate to use in this experiment in order to see if there is a difference in the two population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely perform well in this…

-Four Day School Week- I bet you would love a four day school week, but is it unhealthy ? Yes actually it is very unhealthy for us and I will tell you why.

pie chart, respectively. According to the “Histogram of Test Scores”, Appendix A(2), the data can be described as normally distributed. The descriptive statistics result for the variable “Test Scores” in Appendix A (1), also indicates that the distribution is symmetric around the mean, with the mean value of 52.6 points and the median 51 points. This shows that the data values appear to be close to the center of the data and that…

random. Students answers mattered only as a success or failure in whether they planned to attend college or not. In addition, n p̂ >10 at 26 people and n q̂ >10 at 474 people. Because the conditions are satisfied, a Normal Model for the sampling distribution of the proportions will be used for a one-proportion z-test. This will be a two-tailed tests as we are attempting to determine if the proportion of students who enlist in the military is different then the 90’s .045. This is…

Despite the extraordinary development of the world in the 200 years I have not been around, with tremendous technological and ideological advances that brought about wealth unheard of back in my time, it is disheartening to see that some mercantilist ideas and practices are alive and well.
