In a hypothesis test with hypotheses Ho : M 2 80 and H1 : M

In a hypothesis test with hypotheses Ho : g 2 80 and HI : g < 80, a random sample of 101 elements selected from the population produced a mean of 75.3. Assume that o = 26.4, and that the test is to be made at the 3% significance level. What is the critical value of z? -1.88 -2.17 2.17 O 1.88 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?
