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. X1 = 26, S1 = 2, n1 = 20, X2 = 27, $2 = 6, n2 = 10 a. Left-tailed test, a = 0.05 b. 90% confidence interval a. What are the hypotheses for the t-test? OA. HO: M1 = H2 OB. HO: MISH 2 Ha: My H2 OC. Ho: My = H2 OD. HO: H1 = H2 Ha: H1 > 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. Do not reject Ho. There is sufficient evidence that u, is less than H2. O B. Reject Ho. There is sufficient evidence that u, is less than H2. O C. Do not reject Ho. There is insufficient evidence that u, is less than H2- O D. Reject Ho. There is insufficient evidence that u, is less than H2- b. The 90% confidence interval is from |to ].
