For each of the problems that follow, you will be asked to conduct hypothesis tests. For each problem clearly state the hypothesis test to be conducted using proper notation. State the test score and the p- value. Say whether to reject or fail to reject the null hypothesis. Then clearly, in plain English and in the context of the problem, state your conclusion. Use a = 0.05 unless stated otherwise in the problem. 9. In 1990, the mean height of women 20 years of age or older was 63.7 inches based on data from the CDC, with a standard deviation of 3.4 inches.
