Given the accompanying null hypothesis, alternative hypothesis, and sample information, complete parts a and b below. Sample 1 Sample 2 Hoi of so? n, = 11 n2 = 22 s3 = 1,459 = 1,248 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< or F> reject Ho, otherwise do not reject Ho. O B. 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. Reject the null hypothesis. There is sufficient evidence to conclude that the first population variance is greater than the second population variance. O B. Reject the null hypothesis. There is insufficient evidence to conclude that the first population variance is greater than the second population variance. OC. 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 D. Do not reject the null hypothesis. There is sufficient evidence to conclude that the first population variance is greater than the second population variance.
