Question
Body temperatures Most people think that the “normal”
adult body temperature is 98.6°F. That figure, based on
a 19th-century study, has recently been challenged. In
a 1992 article in the Journal of the American Medical
Association, researchers reported that a more accurate
adult body temperature is 98.6°F. That figure, based on
a 19th-century study, has recently been challenged. In
a 1992 article in the Journal of the American Medical
Association, 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
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 body
temperatures to be? Explain.
b) What fraction of people would be expected to have
body temperatures above 98.6°F?
