a. A survey of first-year college students asked “About how many minutes do you study on a typical weeknight?” The mean response of 463 students was ž = 118 minutes. Researchers want to test the claim that students study less than 2 hours (120minutes) each night. State the null and alternative hypothesis. b. In context of this example, explain what each of the following mean i. Type I error ii. Type II error jii. Correct decision Suppose that the results of carrying out the hypothesis test lead researchers to accept the null hypothesis. Classify the conclusion by error type or as a correct decision if in fact... i. the mean study time is 2 hours. ii. the mean study time is less than 2 hours. d. The mean response of 463 students was ž = 118 minutes. Researchers know that the study time has a standard deviation o=65 minutes. Does the study provide good evidence at the 5% significance level that the students claim to study less than 2 hours each night? C.
