Assume that the population standard deviation is =0.6. If appropriate, perform a hypothesis test at the a=0.01 level to determine whether the mean GPA for business students differs from the mean GPA at the whole university. What do you conclude? Use the P-value method with the TI-84 calculator. State the null and alternate hypotheses. HoH 2.85 H2.85 This hypothesis test is a two-tailed V test. Part: 2/5 Part 3 of 5 Compute the P-value of the test statistic. Round the answer to at least four decimal places. P-value= X 5
