with medicine y for a month; then the subjects' cholesterol level was measured. A
significance test was conducted at the 0.01 level for the mean difference in cholesterol levels between medicine X and medicine Y. The test resulted in t - 2.73 and p = 0.003. If the alternative hypothesis in
question was Mo: px - WY* 0, where wx equals the mean cholesterol level for subjects taking medicine X and by equals the mean cholesterol level for subjects taking medicine Y, what conclusion can be drawn? (2
