Question 7 6 pts A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, u, of the population from which the sample was drawn. Use the critical-value approach. Sample mean = 43.5 s = 5.9 n = 15 a = 0.05 Ho: H = 32.6 H1: H # 32.6 1. The test statistics is (Round to three decimal places) 2. The critical value(s) is/are (If there are two critical values separate each with a comma.) 3. The decision is to the null hypothesis. (Enter R if you reject and enter F if you fail to reject) D Question 8 6 pts A sample mean, sample standard deviation, and sample size are given.
