Question

BMI. 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?
(b) A BMI less than 18.5 is considered to be underweight. What proportion of
women are underweight?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
