le 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 *4 = 27, 8, = 4, ng = 15, X2 = 29, 52 = 9, n2 = 25 a. Left-tailed test, a = 0.05 b. 90% confidence interval d a. What are the hypotheses for the t-test? OA. HOH = H2 H:H, <H2 OC. H: H 512 Hai Hy >th OB. Hy: H4=H2 H:H*12 OD. Ho HH2 H:H>12 Find the test statistic. t= (Round to three decimal places as needed.) Find the critical value -=(Round to three decimal places as needed.) What is the conclusion of the hypothesis test? O A. Do not reject Ho. There is sufficient evidence that is less than H2 OB. Reject Ho. There is insufficient evidence that Hy is less than Hy dance that is less than a
