Using the Normal Distribution · Exercise 25
The percent of fat calories that a person in America consumes each day is normally distributed with a mean of about 36 and a standard deviation of 10. Suppose that one individual is randomly chosen. Let X = percent of fat calories.
(a) X ~ _____(_____,_____)
(b) Find the probability that the percent of fat calories a person consumes is more than 40. Graph the situation. Shade in the area to be determined.
