Provided below are summary statistics for independent simple random samples from two populations. Use the pooled t-test and the pooled t-interval procedure conduct the required hypothesis test and obtain the specified confidence interval. X, = 20, s, = 4, n, = 21, x, = 24, s, = 5, n, = 15 a. Left-tailed test, a 0.05 b. 90% confidence interval .... a. What are the correct hypotheses for a left-tailed test? O A. Ho: H1 = H2 Ha: 41> H2 O B. Ho: H1 = P2 Ha: H1 H2 Ha: H1 = 42 Compute the test statistic. t%3= E(Round to three decimal places as needed.) Determine the P-value. P = (Round to four decimal places as needed.) Since the P-value is V than a, V Ho.
