a. What assumption must be made concerning the population in order to test a hypothesis about g?? O A. The population has a normal distribution. O B. The population has a chi-square distribution. O C. There are no assumptions. b. Suppose the assumptions in part a are satisfied. Test the null hypothesis of = 1 against the alternative hypothesis o? > 1. Use a = 0.05. Calculate the value of the test statistic. x2 = (Round to two decimal places as needed.) Find the rejection region for the test. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to four decimal places as needed.) OA. X2 O c. x2 Make the appropriate conclusion. Choose the correct answer below. O A. Do not reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that the population variance is more than 1. O B. Reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that the population variance is more than 1. O C. Reject Ho. There is insufficient evidence at the a = 0.05 level of significance to conclude that the population variance is more than 1. O D. Do not reject Ho. There is insufficient evidence at the a = 0.05 level of significance to conclude that the population variance is more than 1.c. Suppose the test statistic is y" = 16.81. Use the accompanying table to find the approximate p-value of the test. p-value = d. Test the null hypothesis of = 1 against the alternative hypothesis of # 1. Use a = 0.05. Calculate the value of the test statistic. x2 = (Round to two decimal places as needed.) Find the rejection region for the test. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to four decimal places as needed.) OA. x? > O B. Make the appropriate conclusion. Choose the correct answer below. O A. Reject Ho. There is insufficient evidence at the a = 0.05 level of significance to conclude that the population variance is not 1. O B. Do not reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that the population variance is not 1. O C. Do not reject Ho. There is insufficient evidence at the a = 0.05 level of significance to conclude that the population variance is not 1. O D. Reject Ho. There is sufficient evidence at the o = 0.05 level of significance to conclude that the population variance is not 1.Arandom sample of seven measurements gave )_
