A study of a population showed that males body temperatures

A study of a population showed that males? body temperatures are approximately Normally distributed with a mean of 98.4 degree F and a population standard deviation of 0.50 degree F. What body temperature does a male have if he is at the 98th percentile? Draw a well-labeled sketch to support your answer. He has a body temperature of F. (Round to one decimal place as needed.) Choose the correct graph below.

Solution

The z score that is closest to 98th percetile is 2.05.

Thus the X score at 98th percentile is: 98.4+2.05*0.50=99.425

The graph B is the correct graph in support to the answer.
