Thirty men and thirty women with knee pain were subjects in an experiment to determine the effectiveness of a new pain medication. Fifteen of the 30 men and 15 of the 30 women were chosen randomly to receive the new drug. The remaining 15 men and 15 women received a placebo. The decrease in pain was measured for each subject. Then the design of experiment is
