Body temperatures Most people think that the “normal”adult body temperature is 98.6°F. That figure, based ona 19th-century study, has recently been challenged. Ina 1992 article in the Journal of the American MedicalAssociation, researchers reported that a more accurate figure may be 98.2°F. Furthermore, the standard devia-tion appeared to be around 0.7°F. Assume that a Normal model is appropriate.a) In what interval would you expect most people’s bodytemperatures to be? Explain.b) What fraction of people would be expected to havebody temperatures above 98.6°F?c) Below what body temperature are the coolest 20% ofall people?

The 98.6 degree standard for human body temperature was derived by a German doctor in 1868. In an attempt to verify his claim, Mackowiak, Wasserman, and Levine22 took temperatures from 148 healthy peopleover a 3-day period. A data set closely matching the one in Mackowiak’s article was derived by Allen Shoemaker, and appears in the Journal of Statistics Education.23 The body temperatures for these 130 individuals are shown in the relative frequency histogram that follows. See Attachment a. Describe the shape of the distribution of temperatures.b. Are there any unusual observations? Can you think of any explanation for these?c. Locate the 98.6-degree standard on the horizontal axis of the graph. Does it appear to be near the center of the distribution?
