Question
ow much more effective is exercise plus drug treatment in reducing the rate of heart attack among women aged 60 and above compared to drug treatment alone? A research was conducted to check whether drug treatment plus exercise is better in reducing heart attacks compared to drug treatment alone. A completely randomized experiment was done to 1000 healthy females aged 60 and above. Five hundred of subjects received drug treatment only, while the remaining five hundred must do exercise while receiving the treatment. What must be the most appropriate inference method for the original research question ?
a.two-sample t interval for μ1−μ2μ1−μ2
b.one-sample z test for a proportion.
c.two-sample z test for p1−p2p1−p2
d.two-sample z interval for p1−p2p1−p2
e.two-sample t test for μ1−μ2μ1−μ2
