You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. H0:u550 Ha:u>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) Q = 52.2 Find the value of the test statistic. x State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tail.) test statistic S NONE test statistic 2 J State your conclusion. O Reject H0. There is insufficient evidence to conclude that M > 50. Q Do not reject HO. There is insufcient evidence to conclude that It > 50. Reject H0. There is sufficient evidence to conclude that M > 50. 0 Do not reject H0. There is sufficient evidence to conclude that u > 50. (b) = 51 Find the value of the test statistic. 0.968 'p State the critical values for the rejection rule. [If the test is one-tailed, enter NONE for the unused tail.) test statistic S J test statistic 2 J State your conclusion. O Reject H0. There is insufficient evidence to conclude that ,u > 50. 6) Do not reject H0. There is insufcient evidence to conclude that ,u > 50. O Reject H0. There is sufficient evidence to conclude that ,u > 50. 0 Do not reject H0" There is sufficient evidence to conclude that p > 50. J (c) 2 = 51.9 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 5 J test statistic 2 J State your conclusion. O Reject H0. There is insufficient evidence to conclude that ,u > 50. 0 Do not reject H0. There is insufcient evidence to conclude that ,u > 50. EReject H0. There is sufficient evidence to conclude that ,u > 50. 0 Do not reject HO. There is sufficient evidence to conclude that p > 50. 'I
