Body Mass Index.  Body mass index I can be used to determine whether an individual has a healthy weight for his or her height. An index in the range 18.5–24.9 indicates a normal weight. Body mass index is given by the formula, or model,

$I=\frac{703W}{H^2}$,

where W is weight, in pounds, and H is height, in inches. Use this formula for Exercises 71 and 72.
