Body Mass Index (BMI) is equal to weight in kilograms divided by height in meters squared. A study by the National Center for Health Statistics suggested that women between the ages of 20 and 29 in the United States have a mean BMI of 26.8 with a standard deviation of 7.4. Let us assume that these BMIs are normally distributed.

A) A BMI of 30 or greater is classified as being overweight. What proportion of women in this age range are overweight according to this definition. Use the 4 step process discussed in class (state the problem, standardize the value, determine the probability, and state conclusion). (4 points)

B) A BMI of less than 18.5 is classified as underweight. What proportion of women are underweight? Use the 4 step process discussed in class (state the problem, standardize the value, determine the probability, and state conclusion).(4 points)
