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 = 11, S₁ = 2.3, n₁ = 17, x₂ = 14, s₂ = 2.3, n₂ = 17 a. Two-tailed test, a = 0.10 b. 90% confidence interval a. First, what are the correct hypotheses for a two-tailed test? OA. Ho: H1 H₂ H₂: H₁ = H₂ O C. Ho: Hq #H2 H₂: H₁ = H₂ OE. Ho: H₁ H₂ H₂: H₁ = H₂ Next, compute the test statistic. t= = (Round to three decimal places as needed.) Now determine the critical values. #ta/2= ± (Round to three decimal places as needed.) OB. Ho: H1 H2 Hai H1<H2 OD. Ho: H₁ Hai H₁ H2 H₂ OF. Ho: H1 H2 Hai H1> H2. 63

What is the conclusion of the hypothesis test? Since the test statistic in the rejection region, 0. b. The 90% confidence interval is from to (Round to three decimal places as needed.) Ho.
