Suppose that you tested the null hypothesis H0: ?=20 against the alternative hypothesis H1: ??20 for a random sample of n=81 observations, x?=18, s=15. The value of the test statistics is -3.6 -1.2 -2.4 -0.133

Suppose you have the following null and alternative hypotheses: H0: μ =8.3 H1: μ ≠ 8.3 You take a sample of 30 observations, and find a sample mean of 7.3 with a standard deviation of 2.0. What is the value of the test statistic?
