Question
In 1982 The Physicians' Health Study (a randomized clinical trial) was begun in order to test whether low-dose aspirin was beneficial in reducing myocardial infarction (heart attacks). The study population consisted of over 22,000 male physicians who were randomly assigned to either low-dose aspirin or a placebo (an identical looking pill that was inert). They followed these physicians for about five years. Some of the data is summarized on the table shown below. Treatment Myocardial Infarction No Infarction Total Aspirin 239 10, 898 11, 137 Placebo 437 10, 795 11, 232 What is the probability that a physician would have a myocardial infarction after using low-dose aspirin during the study? 0.02146 0.02347 0.25641 0.26972Explanation / Answer
as total number of people having Myocardial Infraction given using Aspirin are 239 out of 11137
hence probability =239/11137=0.02146
hence option 1 is correct.
