Provided below are summary statistics for independent simple random samples from two populations. Use the pooled t-test and the pooled t-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval X1 = 10, s1 = 2.4, n1 = 13, X2 = 12, $2 = 2.4, n2 = 13 a. Two-tailed test, a = 0.10 b. 90% confidence interval a. First, what are the correct hypotheses for a two-tailed test? OB. HO: H1 = H2 OA. HO: H1 = H2 Ha : My * H2 Ha: My H2 Ha : H1 > H2 Ha: M1 = H2 Next, compute the test statistic. t= (Round to three decimal places as needed.) Finally, determine the P-value. P=(Round to four decimal places as needed.) What is the conclusion of the hypothesis test? Since the P-value is than a , b. The 90% confidence interval is from to]. (Round to three decimal places as needed.)
