Consider the following hypothesis test with n = 18, s =7.6, and x = 64.5. Ho: H= 61 HA: H # 61 0 = 0.05 a. State the decision rule in terms of the critical value of the test statistic. b. State the calculated value of the test statistic. c. State the conclusion. . .... a. State the decision rule. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) O A. Reject the null hypothesis if the calculated value of the test statistic is greater than the critical value of . Otherwise, do not reject. O B. Reject the null hypothesis if the calculated value of the test statistic is less than the critical value of or greater than the critical value of . Otherwise, do not reject. O C. Reject the null hypothesis if the calculated value of the test statistic is less than the critical value of . Otherwise, do not reject. b. State the calculated value of the test statistic. (Round to two decimal places as needed.) c. State the conclusion. Choose the correct answer below. O A. Do not reject the null hypothesis. There is sufficient evidence that the mean is not equal to 61. O B. Reject the null hypothesis. There is not sufficient evidence that the mean is not equal to 61. O C. Do not reject the null hypothesis. There is not sufficient evidence that the mean is not equal to 61. O D. Reject the null hypothesis. There is sufficient evidence that the mean is not equal to 61
