Provided below are summary statistics for independent simple random samples from two populations. Use the nonpooled t-test and the nonpooled t-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval. Xq = 17, $1 = 5, n1 = 10, X2 = 16, $2 = 4, n2 = 25 a. Right-tailed test, a = 0.05 b. 90% confidence interval a. What are the hypotheses for the t-test? O A. HOM1 = H2 O B. HO H1 = H2 Ha H1 > H2 Hai My # H2 O C. Ho- H1 = H2 OD. HO H1 2 H2 Hai My = H2 Ha: My = H2 Find the test statistic. t=(Round to three decimal places as needed.) Find the P-value. P=(Round to four decimal places as needed.) What is the conclusion of the hypothesis test? O A. Reject Ho. There is sufficient evidence that u, is greater than #2. O B. Do not reject Ho. There is insufficient evidence that my is greater than #2- O C. Do not reject Ho. There is sufficient evidence that my is greater than #2 O D. Reject Ho. There is insufficient evidence that why is greater than H2
