A well-knоwn study оf 32,000 mаle physiciаns wаs cоnducted to determine if taking aspirin daily makes a difference in the likelihood of someone getting a heart attack. Half of those 32,000 physicians were given a regular dose of aspirin while the other half was given placebos. Six years later, among those who took aspirin, 128 suffered heart attacks while among those who took placebos, 240 suffered heart attacks. Does it appear that the aspirin can make a difference in the proportion of physicians having heart attacks in the groups? Use α = 0.01 level of significance.
