Statistical Methods Assignment Research Paper Example | Topics and Well Written Essays - 1000 words

Statistical Methods Assignment - Research Paper Example Since this is a weight reduction study, we did a one-directional t test. Results showed that the diet resulted in a significant decrease in weight, both for a 90% and 95% confidence level. In both cases, it is reasonable to say that two-thirds of the general population agrees with the principle of University top-up fees. The hypothesized p is included in both intervals. We, therefore, do not reject the null hypothesis. .. : 0.05 p = 2*0.0096 = 1 - 0.9808 = 0.0192 The test shows that there is a significant statistical difference between the sample mean and the hypothesized mean, on a 95% confidence level. We, therefore, reject the null hypothesis. Question 6 sample size 121 degree of freedom 120 sample mean 47.50 critical t 1.658 sample standard deviation 7.50 90% confidence interval (46.37, 48.63) Assuming that the population standard deviation is equal to the sample standard deviation, the confidence interval becomes: (46.38, 48.62) The two intervals do not seem to have a significant difference between them. This is a result of having a large sample size. As the sample size increases, the difference between the two intervals is also expected to significantly increase, resulting to large errors. Question 7 t ratio 3.364 alpha () critical t 0.05 2.306 reject H0 0.10 1.860 reject H0 In this test, we assume that the sample standard deviation approximates that of the population without any significant statistical difference. Since this is a weight reduction study, we did a one-directional t test. Results showed that the diet resulted in a significant decrease in weight, both for a 90% and 95% confidence level. Question 8 T 680 N 1050 T/n 0.648 p 0.667 standard deviation 0.228 Test Statistic 1.29 (1.29) 0.9015 p value 0.1970 95% confidence interval (0.619, 0.677) 90% confidence interval (0.623, 0.672) In both cases, it is reasonable to say that two-thirds of the general population agrees with the principle of University top-up fees. The hypothesized p is included in both intervals. We, therefore, do not reject the null hypothesis. Question 9 To estimate a population proportion p with a 95% confidence

Globalizations has spawned a new frontier in the fight for human Essay

Globalizations has spawned a new frontier in the fight for human rights protections - Essay Example The United States is a super power because of the fact that it imperialized and was able to control its colonies compared to its European predecessors.

With the labor force ready to combat poverty in third world countries, the economical behavior of the nation has undoubtedly suffered because of the factors mentioned above. chaos as millions of poor workers were frustrated with working conditions as corruption loomed in city government. Packed in small quarters, these workers are living in a prison in essence with little chance of surviving. Individuals struggle to support households and have no funds to invest in their business. Women and children get exploited the most as they have no rights in developing countries. Moreover, the rich get richer in a pendant system where there is no paradigm of middle class. This causes issues because customers do not have p urchasing power or rights in any manner. It is clear that there has to be a plant to rectify this issue. Women and children needs rights to set hours of constant workload. The International Human Right Services is
