Example 152 Tech: A study was conducted to determine the factor that reduces LDL cholesterol the most: medication, diet, or exercise. Twenty-seven patients at a hospital with comparable levels of LDL cholesterol are randomly assigned to each treatment group. After eight weeks, the drop in LDL cholesterol for each patient was measured. Fill in the missing parts of the ANOVA table, answer the set of questions that follow, and use a 5% significance level to test the claim that all three of the treatments produce the same drop in LDL cholesterol.
