A sample of 100 provided a sample mean of 77.5. The population standard deviation is known to be 15. (a) Compute the value of the test statistic. (Round your answer to two decimal places.) (b) Determine the p-value; and using a = 0.063, test the above hypotheses. Find the p-value. (Round your answer to four decimal places.) p-value= State your conclusion. Reject Ho. There is sufficient evidence to conclude that is less than 80. O Reject Ho. There is insufficient evidence to conclude that is less than 80. O Do not reject Ho. There is sufficient evidence to conclude that u is than 80. 82°F Sunny O Do not reject Ho. There is insufficient evidence to conclude that is less than 80. (c) Using the critical value approach and a = 0.063, test the hypotheses. Determine the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistics test statistic 2 State your conclusion. Reject Ho. There is sufficient evidence to conclude that ju is less than 80. O Reject Ho. There is insufficient evidence to conclude that is less than 80. O Do not reject Ho. There is sufficient evidence to conclude that is less than 80. LAN
