Consider the following hypothesis test. Hoi H = 15 H: u = 15 A sample of 50 provided a sample mean of 14.09. The population standard deviation is 3. (a) Find the value of the test statistic. (Round your answer to two decimal places.) -2.14 (b) Find the p-value. (Round your answer to four decimal places.) p-value = 0.0324 (c) At a = 0.05, state your conclusion. Reject H,. There is sufficient evidence to conclude that u # 15. Reject H,. There is insufficient evidence to conclude that u + 15. Do not reject Ho: There is sufficient evidence to conclude that u = 15. Do not reject Ho: There is insufficient evidence to conclude that u = 15. (d) State the critical values for the rejection rule. (Round your answers to two decimal places. If the test is one-tailed, e NONE for the unused tail.) test statistic s test statistic 2 State your conclusion. O Reject Ho. There is sufficient evidence to conclude that u = 15. Reject Ho. There is insufficient evidence to conclude that u = 15. Do not reject Ho: There is sufficient evidence to conclude that u = 15. Do not reject Ho. There is insufficient evidence to conclude that u = 15.
