A Study of 6,600 Men Found That Those Who Consumed

question 31

Multiple Choice

A study of 6,600 men found that those who consumed a moderate amount of alcohol (one drink or less per night) have lower mortality (on the average) than those who drink none. Is this good evidence that drinking a moderate amount causes lower mortality?

• A) Yes, because the study is an experiment.
• B) No, because people who drink a moderate amount may differ from nondrinkers in other ways, such as income and exercise, that affect mortality.
• C) Yes, because the sample is so large that the margin of error will be quite small.
• D) No, because we can't generalize from 6,600 people to the millions of adults in the country.
