Comprehensive Exam Many graduate programs require students to pass a comprehensive exam (or qualifying exam, or something equivalent) before being admitted into candidacy to receive the degree. Suppose the population consists of all comprehensive exams (or equivalent) that are given to students in graduate programs, and of interest is the mean number of questions asked on the comprehensive exams. It is conjectured that the mean number of questions asked on all comprehensive exams is 8, and of interest is to test this conjecture versus the alternative that the mean number of questions asked on all comprehensive exams is different from 8 MacBook Air 1 2 State the appropriate null and alternative hypotheses that should be tested. H: 8 versus H: 8 Ho: μ= 8 versus H₂: μ# 8 Ho: μ= 8 versus H₂: μ 8 Consider the information provided and the hypotheses specified in question 1. A simple random sample of 81 comprehensive exams was selected and the number of questions asked on each comprehensive…
