A drug thought to increase strength was given to three men, with nine other men acting as controls. The results in arbitrary units were 19, 20, and 21 for the men with the drug and 10, 11, 12, 13, 14, 15, 16, 17, and 18 for the men without the drug. The drug was also tried on nine women, with three women acting as controls. The results were 5.5,6.0,6.5,7.0,7.5, 8.0, 8.5,9.0, and 9.5 for women with the drug and 4.0, 4.5, and 5.0 for women without the drug. Perform appropriate tests to see if there is convincing evidence that the drug works for men and for women. Combine the results for both men and women and repeat your statistical test. Explain your result. P-963
