The effect of exercise and diet on body weight is being studied. Researchers at a major university have a list of 2,500 women students aged 18-25 willing to participate in a study involving controlled diets and amounts of exercise for a six week period. Participants in the study will receive $300 as a compensation for the time spent in the study.
a. Describe how a simple random sample of 30 women can be selected from the pool of 2,500 available for the study. b. Comment on whether the results of this study can be generalized to all adult women in the United States.
