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 = 14, S₁ = 3, n₁ =15, x₂ = 11, S₂ = 9, n2 = 25 a. Right-tailed test, α = 0.05 b. 90% confidence interval Find the test statistic. t= (Round to three decimal places as needed.) Find the P-value. P= (Round to four decimal places as needed.) What is the conclusion of the hypothesis test? O A. Do not reject Ho. There is insufficient evidence that μ, is greater than μ₂. B. Reject Ho. There is insufficient evidence that μ, is greater than μ₂. O C. Do not reject Ho. There is sufficient evidence that μ, is greater than μ₂. O D. Reject Ho. There is sufficient evidence that μ, is greater than μ₂. b. The 90% confidence interval is from to (Round to three decimal places as needed.)
