Problem 2

A study was conducted to determine the factor that reduces blood pressure the most, medication, diet, or exercise. Fifteen patients at a hospital with comparable levels of high blood pressure are randomly assigned to each treatment group. After eight weeks, the drop in systolic blood pressure for each patient was measured. Use the data below and a 5% significance level to construct an ANOVA table to test the claim that all three of the treatments produce the same drop in blood pressure.
