Find t statistic, critical values, conclusion hypothesis test, 90% confidence interval

Homework: Ch 10 Sec. 3 Part 2 of 5 Points: 0.75 of 5 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 *1 = 13, S1 = 2, n, = 15, X, = 12, 5, = 3, n2 = 10 a. Right-tailed test, a = 0.05 b. 90% confidence interval a. What are the hypotheses for the t-test? OB. Ho H1 = H2 A. Ho: H1 = H2 Ha- H1 = H2 & D. HO H1 = H2 OC Ho H12H2 Ha H1 > H2 Ha H1
