A study occurred to test whether taking aspirin can reduce the chance of having a heart attack. Over 20000 male medical doctors aged 40 through 84 were given a 325 mg tablet every other day. Just over half of the doctors (11037) were given aspirin tablets; the rest (11034) were given placebos. There were 104 heart attacks in the aspirin group and 189 in the placebo group. Analyze!!!! (By which I mean perform a relevant hypothesis test and/or construct an appropriate confidence interval.)
