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. x = 14, s = 2.4, n = 12, = 16, $2 = 2.2, n = 12 a. Two-tailed test, a = 0.10 b. 90% confidence interval a. First, what are the correct hypotheses for a two-tailed test? A. Ho: H =H2 Ha H1 H2 O C. Ho: H #2 Ha H1 H2 E.
