Question : A few years ago, there was a large study of 22,000 male physicians was conducted to determine if taking aspirin daily reduces the chances of a heart attack. Half of the physicians were given a regular dose of aspirin while the other half was given placebos. Six years later, among those who took aspirin, 106 suffered heart attacks, while among those who took placebos, 188 suffered heart attacks. Did the aspirin seem to work in reducing heart attacks? Conduct the correct test on this data. Use ? = .01 I need to find the sample proportions of ?̂ and n for both of the samples or if it's a sample mean then I find the n, ?̅ and ?̅? for both samples  ?
