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 = 9, S1 =6, n1 = 20, X2 = 12, $2 = 7, n2 = 20 a. Two-tailed test, a = 0.10 b. 90% confidence interval . . . a. What are the hypotheses for the t-test? OB. Ho: My = H2 OA. Ho: My = H2 Ha: My H2 OD. Ho: H1 2 H2 O C. Ho: H1 = H2 Ha: H1
