An experiment was conducted to test the effect of a new cholesterol medicine. Fifteen people were treated with medicine X and 15 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
points)
There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.
There is not a significant difference in mean cholesterol level when using medicine X and medicine Y.
There is sufficient evidence that medicine X towers cholesterol levels more than medicine Y.
The proportion of subjects who lowered their cholesterol level with medicine X is greater than the proportion of subjects who lowered their cholesterol level with medicine Y.
There is insufficient evidence that the proportion of people who lowered cholesterol level on medicine X and Y is different.
