Question

7. Below is a drawing of a Standard Normal Distribution, a bell-curve density function. Vertical lines have been drawn for every half of a standard deviation away from the mean. Illustrate the calculations you performed in question 6 as follows:

[a] draw a vertical line that divides “underweight” and “normal” weights (i.e., BMI = 18.5),

[b] draw a vertical line that divides “normal” weight and “overweight” (i.e., BMI = 25),
[c] draw a vertical line that divides “overweight” and “obese” (i.e., BMI = 30).
