It was begun in 1982 and involved 22,071 male physicians between the ages of 40 and 81.

This was a randomized cinical trial which means each subject in the study was randomly assigned one of two treatments-taking an aspirin every other day or taking a placebo every other day About 11,000 subjects were randomly assigned to take an aspirin every other day, and about 11,000 subjects were randomly assigned to take a placebo every other day The study lasted S years. At the end of t group taking a placebo. They found 0 9 of the group taking asp in and 1.7% of the gro p taking a placebo had heart attacks. They used statistical methods to predict the US men aged 40 or older who take aspirin every other day have a lower risk of having a first heart attack compared to men who dont take an aspirin every other day. Match each term with the aspect of the study to which it refers the study, the researchers described their results by reporting the percentage of heart attacks in the group taking aspirin and in the с . Inference a The sample, the randomization (random assignment of treatment), and tne plan te obtain percentages of each group that have heart attacks. Design b. The actual percentages of the people in the sample whe have heart attacks bDescription c. The use of statistical methods to make the prediction that US men aged 40 or older who taie aspirin every other day have a lower risk of having a first heart attack compared to men who dont take an aspirin every other day

Answer #1

2.

Here the sample is the 22071 male physicians.

The subject is a physician under study.

The population is all US males aged 40 or older.

See, the population means the whole where the random sample is to be taken and the group of individuals which are taken for the purpose of the study is the sample. So, here the whole population means all US males aged 40 or older and the 22071 male physicians who are chosen for the study is the sample. Now, each individual of the sample are the subject.
