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. = 22, S = 5, n = 25, X = 27, S = 2, n = 20 a. Left-tailed test, = 0.05 b. 90% confidence interval a. What are the hypotheses for the t-test? OA. Ho: H1 H2 Ha H1 H2 O C. Ho: H=2 Ha H1 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? A. Do not reject Ho. There is sufficient evidence that is less than 2. B. Reject Ho. There is insufficient evidence that is less than - C. Do not reject Ho. There is insufficient evidence that is less than 2. D. Reject Ho. There is sufficient evidence that is less than . b. The 90% confidence interval is from to (Round to three decimal places as needed.)
