Ho: M = 25 Him + 25 x = 28.1, n = 55, 6 = 8.47, a = .01 Appendix A Statistical Tables a. Use the data given to test the following hypotheses. (Round your answer to 2 decimal places, e.g. 15.25.) The value of the test statistic is and we b. Use the p-value to reach a statistical conclusion. (Round your answer to 4 decimal places, e.g. 0.1254.) Since the p-value of is v than a/2 = .005, the decision is to: c. Using the critical value method, what are the critical sample mean values? (Round your answer to 3 decimal places, e.g. 15.254.)
