Consider the following hypothesis test. Ho: MS 50 Ha: H > 50 A sample of 60 is used and the population standard deviation is 8. Use the critical value approach to state your conclusion for each of the following sample results. Use a = 0.05. (Round your answers to two decimal places.) (a) x = 52.5 Find the value of the test statistic. State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tail.) test statistic s test statistic 2 State your conclusion. O Do not reject Ho. There is sufficient evidence to conclude that u > 50. O Do not reject Ho. There is insufficient evidence to conclude that / > 50. O Reject Ho. There is insufficient evidence to conclude that u > 50. O Reject Ho. There is sufficient evidence to conclude that u > 50. (b) x = 51 Find the value of the test statistic. State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tail.) test statistic s test statistic 2 State your conclusion. O Do not reject Ho. There is sufficient evidence to conclude that u > 50. O Do not reject Ho. There is insufficient evidence to conclude that u > 50. O Reject Ho. There is insufficient evidence to conclude that u > 50. O Reject Ho. There is sufficient evidence to conclude that u > 50.(c) x = 51.8 Find the value of the test statistic. State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tail.) test statistic test statistic 2 State your conclusion. O Do not reject H . There is sufficient evidence to conclude that u > 50. O Do not reject H . There is insufficient evidence to conclude that A > 50. O Reject Ho. There is insufficient evidence to conclude that ( > 50. O Reject H . There is sufficient evidence to conclude that u > 50
