Test the claim about the differences between two population variances a and o at the given level of significance a using the given sample statistics. Assume that the sample statistics are from independent samples that are randomly selected and each population has a normal distribution. Claim: o sa3, a 0.05 Sample statistics: s, = 705, n, 3, s, = 368, n, 9 Find the null and alternative hypotheses. OA Ho: o >o Hi o so OC. Hoi o z03 OB. Ho: of so H of >o OD. Hoi of co H of 20 Find the critical value. (Round to two decimal places as needed.) Find the test statistic. (Round to two decimal places as needed.) Choose the correct conclusion below. O A. Reject the null hypothesis. There is enough evidence to reject the claim. O B. Reject the null hypothesis. There is enough evidence to support the claim. O c. Fail to reject the null hypothesis. There is not enough evidence to support the claim. O D. Fall to reject the null hypothesis. There is not enough evidence to reject the claim.

Test the claim about the differences between two population variances a and o at the given level of significance a using the given sample statistics. Assume that the sample statistics are from independent samples that are randomly selected and each population has a normal distribution. Claim: o so, a = 0.05 Sample statistics: s, = 705, n, =3, s = 368, n, = 9 Find the null and alternative hypotheses. OA Hoio> Hạ: o so3 OC. Hoi o z0 H,: o <o O B. Ho: o so OD. Hoi of <o} H, of 20 Find the critical value. (Round to two decimal places as needed.) Find the test statistic. (Round to two decimal places as needed.) Choose the correct conclusion below. O A. Reject the null hypothesis. There is enough evidence to reject the claim. O B. Reject the null hypothesis. There is enough evidence to support the claim. Oc. Fail to reject the null hypothesis.
