Ho:H = 23 H :u # 23 x = 26.3, n = 55, o = 8.48, 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 2.89 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 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.) Critical mean values: Upper value: Lower value
