Body Temperatures Exercise 16 in Section 2-2 referred to Data Set 4 in Appendix B.

Using the frequency distribution of the body temperatures for midnight on the second day (with 8 classes beginning with a lower class limit of 96.5 and a class width of 0.4°F), construct the corresponding histogram. What does the distribution suggest about the common belief that the average body temperature is 98.6°F? If the subjects are randomly selected, the temperatures should have a distribution that is approximately bell-shaped. Is it?
