I need help with these questions. I did part A with the regressional analysis and got 92.5% for the coefficient determination.
The data below are stress-test scores from 6 nurses from the Emergency Care (EC) unit and 6 nurses from the Long Term (LT) care unit who were randomly selected for the study. The investigator wants to test, at the 5% level, whether there is a difference in stress test scores in the EC group and the LT group. EC LT 5 2 9 3 8 5 10 6 7 4 6 2 State the hypotheses. What statistical test should be used to determine if there is a difference in stress scores between EC and LT nurses? Determine the appropriate critical value and set up the decision rule. Compute the test statistic. Interpret your results. Give your conclusion.
A professor of women's studies is interested in determining if stress affects the menstrual cycle. Ten women are randomly sampled for an experiment and randomly divided into two groups. One of the groups is subjected to high stress for two months while the other lives in a relatively stress-free environment. The professor measures the menstrual cycle (in days) of each woman during the second month. The following data are obtained. High stress 20 23 18 19 22 Relatively stress free 26 31 25 26 30 Assume you are evaluating H0 using the t test. The df for determining tcrit are _________.

Medical research has shown that repeated wrist extensions beyond 20 degrees increase the risk of wrist and hand injuries. Each of 24 students at a university used a proposed new computer mouse design, and while using the mouse, each student's wrist extension was recorded.

(25.294 x 26.706 (b) What assumptions are required in order for it to be appropriate to generalize your estimate to the population of students at this university? No, we cannot generalize the estimate to any population as we have less than 30 students. O Yes, the assumption would have to be made that the 24 students in the study formed a random sample of people in the country. O Yes, the assumption…
