please find: t=determine the critical values of ta/2confidence interval

Provided below are summary statistics for independent simple random samples from two populations. Us to conduct the required hypothesis test and obtain the specified confidence interval. x1 = 13, s, = 5, n, = 15, X2 = 16, $2 = 3, n2 = 15 a. Two-tailed test, a =0.01 b. 99% confidence interval a. What are the hypotheses for the t-test? OA. Ho: Hy = H2 O B. Ho: H1 2 H2 Ha: Hy > H2 Ha: Hy
