The body mass index is calculated by dividing a person's weight by the square of his or
her height; it is a measure of the extent to which the individual is overweight. A
researcher would like to test the hypothesis that men who develop diabetes have a
higher BMI than men of similar age who do not. A literature review indicates that in
healthy men, BMI is normally distributed, with a mean of 25 and a standard deviation of
2.7. The researcher proposes to measure 25 normal and 25 diabetic men. It is felt that
a difference in average BMI of 2.7 (that is, one standard deviation) would be clinically
meaningful. What is the power of the proposed study? Using SAS
