In a hypothesis test with hypotheses He : ,u = 24 and H1 : ,u a 24, a random sample of 38 elements selected from the population produced a mean of 24.1. Assume that a = 5.3, and that the test is to be made at the 1% signicance level. What are the critical values of z? ' -2.07 and 2.07 ' -2.17 and 2.17 ' -2.33 and 2.33 ' -2.58 and 2.58 What is the value of the test statistic, z, rounded to three decimal places? What is the p-value for this hypothesis test, rounded to four decimal places? Should you reject or fail to reject the null hypothesis in this test? A V
