Assume that you have a sample of n, = 6, with the sample mean X, = 46, and a sample standard deviation of S, = 6, and you have an independent sample of n2 = 8 from another population with a sample mean of X2 = 37 and the sample standard deviation S2 = 7. Assuming the population variances are equal, at the 0.01 level of significance, is there evidence that H1 > H2? . . . . . Determine the hypotheses. Choose the correct answer below. OA. HO: My SH2 OB. HO: H1 > H2 H1: 1 1 > H2 Hy : My S H 2 O C. Ho: H1 = H2 OD. HO: My # H2 Hy: My # H2 H1: 1 1 = H2 Find the test statistic. tSTAT = (Round to two decimal places as needed.) Find the p-value. p-value = (Round to three decimal places as needed.) Choose the correct conclusion below. O A. Reject Ho. There is sufficient evidence that Hy > H2. O B. Do not reject Ho. There is insufficient evidence that My > H2. O C. Do not reject Ho. There is sufficient evidence that My > H2. O D. Reject Ho. There is insufficient evidence that My > H2
