1. Calculate descriptive statistics for all of the quantitative variables. 2. For your data scenario, write the null hypothesis in words (not symbols) for each of the following questions: a. Before the drug trial even began, was there already a difference in happiness among males vs females? b. Does this drug affect a patient's vision? c. Suppose the change in cholesterol the FDA is concerned with when approving a drug is an increase of 6 points or more for "many" patients. Define "many" as 25%. (Assume the FDA believes a drug is "dangerous unless determined to be safe."

3a, 3b, 3c. Write null and alternative hypotheses in symbols for each of the questions or studies in step 2a, 2b, and 2c. 4a, 4b, 4c. Conduct each test. For each test, report the sample mean(s) or sample proportion(s), the sample size(s), standard error, test statistic, and p-value. 5a, 5b, 5c. create a two to three sentence summary of each test result with a recommended action for an appropriate audience.
