led in ate 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. *4 = 17,5 = 4. n = 19, x2 = 20, 52 = 3, n2 = 17 a. Left-tailed test, a = 0.05 b. 90% confidence interval nd a. What are the correct hypotheses for a left-tailed test? O A. Ho: P = H2 Hà- Hệ > H2 OC. Ho<H2 H =12 O E. Ho: 11 =12 НАВ, #2 OB.
