Most people think that the "normal adult body temperature is 98.6°F in a more recent study, researchers reported that a more accurate figure may be 97 9°F. Furthermore, the standard deviation appeared to be around 0.4°F Assume that a Normal model is appropriate. Complete parts a through c below.

C. Using the 68-95-99 7 Rule, about 95% of the body temperatures are expected to be between 97.1 °F and 98.7 °F
