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 = 8, S₁ = 4, n₁ =25, x₂ = 13, S₂ = 9, n₂ = 25 a. Two-tailed test, α = 0.01 a. What are the hypotheses for the t-test? O A. Ho: H₁ = H2 Hai H₁ H₂ O C. Ho: H=H2 Hai #H2 Find the test statistic. b. 99% confidence interval t= (Round to three decimal places as needed.) Find the critical values. ±ta/2= ± (Round to three decimal places as needed.) OB. Ho: H₁2 H₂ Hai H₁ <H₂ O D. Ho: H₁ H2 Hai H1<H2 63.
