12. Normal Temperatures In Exercise 15 (Chapter 1 Review), Allen Shoemaker derived a distribution of human body temperatures, which has a distinct mound-shape.14 Suppose we assume that the temperatures of healthy humans is approximately normal with a mean of 37.0 degrees and a standard deviation of 0.4 degrees.

a. If a healthy person is selected at random, what is the probability that the person has a temperature above 37.2 degrees?

b. What is the 95th percentile for the body temperatures of healthy humans?
