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 = 19, S1 = 2, n, = 10, X2 = 13, $2 = 9, n2 = 25 a. Right-tailed test, a = 0.05 b. 90% confidence interval C.. a. What are the hypotheses for the t-test? OA. HO: M1 = H2 OB. HO: My = H2 Hai My H2 OC. HO: M1 = H2 OD. HO: H1 2 H2 Ha: My * H2 Ha: My
