You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. H0: ,4 s 50 Ha: I4 > 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) i = 52.6 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 E test statistic 2 Z] State your conclusion. O Do not reject H0. There is sufficient evidence to conclude that ,4 > 50. O Reject H0. There is sufficient evidence to conclude that [4 > 50. O Reject HO' There is insufficient evidence to conclude that [4 > 50. Q Do not reject H0. There is insufcient evidence to conclude that 14 > 50. (b) E: 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 5 :] test statistic 2 State your conclusion. Q Do not reject H0. There is sufficient evidence to conclude that y > 50. O Reject Ho- There is sufficient evidence to conclude that H > 50. O Reject Ho- There is insufficient evidence to conclude that y > 50. Q Do not reject Ho. There is insufficient evidence to conclude that y > 50. (c) 2 = 51.8 Find the value of the test statistic. :1 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. Q Do not reject H0. There is sufficient evidence to conclude that p > 50. O Reject H0. There is sufficient evidence to conclude that y > 50. O Reject Ho- There is insufficient evidence to conclude that y > 50. Q Do not reject Ho- There is insufficient evidence to conclude that y > 50
