1) Question on the first day questionnaire asked students to rate their response to the question Are you deeply moved by the arts or music?
Assume the population that is sampled is approximately normally distributed.
(a) Using a significance level of 0.05, perform an appropriate t test on the claim that college students have a rating different than from that of a moderate rating of 4 (NOTE: pay attention to your test value). Make sure you write down the null and alternative hypotheses, and indicate the decision on the null hypothesis.
(b) Is the result significant at the 0.01 level? (you do not need to redo the SPSS calculation) 2) For this problem, which gives the responses to question 1, Are you made uncomfortable by loud noises? Students were divided into two groups, those who responded that indicated that they are not a morning person (1-3 rating on question #17) and those who indicated they are a morning person (4-7). Using SPSS, perform a t test on the claim that students who are morning people have a different level of comfort with loud noises than those who are not morning people. Use a significance level of 0.05. Make sure you write down the null and alternative hypotheses, and indicate the decision on the null hypothesis using the language from the In the Literature section of Gravetter and Wallnau (pp332-333).
3) For this problem, Closeness to Parents (data is based on questions 9 and 10). Each row in the table represents scores by the same individual. Using SPSS, perform a t test on the claim that the mean ratings of closeness to mothers and closeness to fathers are different. Use a significance level of 0.05. Make sure you write down the null and alternative hypotheses, and indicate the decision on the null hypothesis. Would the result be significant at the 0.01 level?
