Chapter 6, Problem 28P
Body mass index (BMI) is a measure of obesity. In standard units, it is calculated by the formula
where W is weight in pounds, and H is height in inches. The obesity classification is:
| BMI | Classification |
| Below 18.5 | Underweight |
| 18.5 to 24.9 | Normal |
| 25 to 29.9 | Overweight |
| 30 and above | Obese |
Write a program in a script file that calculates the BMI of a person. The program asks the person to enter his or her weight (lb) and height (in.). The program displays the result in a sentence that reads: “Your BMI value is XXX, which classifies you as SSSS.” where XXX is the BMI value rounded to the nearest tenth, and SSSS is the corresponding classification. Use the program for determining the obesity of the following two individuals:
(a) A person 6 ft 2 in. tall with a weight of 180 lb.
(b) A person 5 ft 1 in. tall with a weight of 150 lb.

Hookworms are parasitic nematodes that live in the intestines of a host. Hookworms do their damage (often fatally) by draining blood
from the intestinal wall. The data below correlate the number of hookworms and the amount of blood lost by that number of worms.

Body mass index (BMI) is a measure of body composition, which can be used to assess if someone is underweight, healthy weight, overweight but not obese, or obese. It is calculated as a
person's weight (measured in Kilograms) divided by his/her height (measured in meters) squared. We recorded 5 students' BMI values and the numbers of hours they exercised in the
past week, as following:

Health The body mass index (BMI) is a number that can be
calculated for any individual as follows: Multiply a person's
weight by 703 and divide by the person's height squared. That is,
703w
B =
where w is in pounds and h is in inches. The National Heart,
Lung and Blood Institute uses the body mass index to determine
whether a person is "overweight" (25 < B< 30) or "obese"
(B = 30). Source: The National Institutes of Health.

and and interpret.
(b) Calculate
(c) Using the factthat 1 in. = 0.0254 m, and 1 lb. = 0.4536 kg.,
transform this formula to handle metric units.
