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 = 20, s1 = 2, n1 = 15, X2 = 11, $2 = 9, n2 = 10 a. Right-tailed test, a = 0.05 b. 90% confidence interval a. What are the hypotheses for the t-test? OA. Ho: H1 = H2 OB. HO: My = H2 Hai My # H2 Ha: My H2 Ha: My
