a. Set up the null and alternative hypotheses for deter- mining whether the mean PAI value, u, for all similar studies of music performance anxiety exceeds 40. b. Find the rejection region for the test, part a, using a = .05. %3D c. Compute the test statistic. d. State the appropriate conclusion for the test. e. What conditions are required for the test results to be valid? f. Locate the p-value for the test on the MINITAB print- out and use it to make a conclusion. (Your conclusion should agree with g. How would your conclusion change if you used a = your answer in part d.) = .01? ual Haalth
