You are given two random samples with the information shown below. Based on these samples, test at a=0.10 whether the true difference in population variances is equal to zero. Item 2 3 4 5 7 9 1 Sample 1 3.7 3.1 Sample 2 9.7 5.9 8 4.5 2.3 5.7 4.4 10.5 5.4 8.8 8.2 3.8 8.1 4.9 6.8 6 Determine the test statistic. F = (Round to four decimal places as needed.) Determine the critical value. The critical F-value is. (Round to three decimal places as needed.) Reach a decision. Choose the correct answer below. 3.1 5.8 State the null and alternative hypotheses. Choose the correct answer below. 10 6.1 8.3 O A. Do not reject the null hypothesis. There is insufficient evidence to conclude that the difference in population variances is not equal to zero. OB. Reject the null hypothesis. There is insufficient evidence to conclude that the difference in population variances is not equal to zero. OC. Do not reject the null hypothesis. There is sufficient evidence to conclude that the difference in population variances is not equal to zero. OD. Reject the null hypothesis.
