Determine whether the study is an experiment or an observational​ study, and then identify a major problem with the study. A study involved​ 22,071 male physicians. Based on random​ selections, 11,037 of them were treated with aspirin and the other​ 11,034 were given placebos. The study was stopped early because it became clear that aspirin reduced the risk of myocardial infarctions by a substantial amount. This is an ____________ because the researchers __________ the individuals. What is a major problem with the​ study? A.. This is a convenience sample with voluntary​ response, which has a high chance of leading to bias. B. The results apply only to individuals with heart disease. C. There is no blinding or​ replication, which has a high chance of leading to bias. D. The results apply only to male physicians.
