Given the accompanying null hypothesis, alternative hypothesis, and sample information, complete parts a and b below. Next q Sample 1 Sample 2 Ho: 07 so? n1 = 15 n2 = 20 HA: 01 02 = 1,366 s 2 = 1,263 a. If a = 0.05, state the decision rule for the hypothesis. (Round to two decimal places as needed.) O A. If the calculated test statistic F , reject Ho, otherwise do not reject Ho. O C. If the calculated test statistic F > , reject Ho, otherwise do not reject Ho. O D. If the calculated test statistic F = , reject Ho, otherwise do not reject Ho. b. Test the hypothesis and indicate whether the null hypothesis should be rejected. Determine the test statistic. F = (Round to two decimal places as needed.) What would you tell the agent if you tested at the significance level of 0.05? O A. Do not reject the null hypothesis. There is sufficient evidence to conclude that the first population variance is greater than the second population variance. O B. Do not reject the null hypothesis. There is insufficient evidence to conclude that the first population variance is greater than the second population variance. O C. Reject the null hypothesis. There is sufficient evidence to conclude that the first population variance is greater than the second population variance. O D. Reject the null hypothesis. There is insufficient evidence to conclude that the first population variance is greater than the second population variance
