An experiment is done to test the effect of a new experimental drug for high cholesterol. A group of 200 volunteers are separated into two groups of 100 each. Both groups are instructed to follow a similar diet and activity level. Group 1 is given the experimental drug daily for 90 days, while Group 2 is given a placebo. The individuals in the groups do not know whether they are taking the new drug or the placebo. All participants are tested at the start of the study for their serum cholesterol levels. The average for Group 1 is 310 mg/dL, and the average for Group 2 is 302 mg/dL. After 90 days, all participants' serum cholesterol is tested with a blood test. The average serum cholesterol level for Group 1 is 299 mg/dL, and the average for Group 2 is 300 mg/dL. Using this information answer the following: a. What is the hypothesis being tested? b. What is the dependent variable? c. What are the independent variables? d. Which variables are controlled? e. Which is the control group? f. Did the experiment produce data that supports the hypothesis? (1 Mark) (1 Mark) (1 Mark) (1 Mark) (1 Mark) (1 Mark)
