Body Temperatures Recall from Activity 12-01 and Exercise 15-3 that the body temperatures (in degrees Fahrenheit) have been recorded for a sample of 130 healthy adults (Shoemaker, 1996). The sample mean body temperature is 98.249°F, and the sample standard deviation is 0.733°F. Number of Adults 25 20 15 10 5- N 5 3 99 23 18 22 20 - 5 2 0- 96.0 96.5 97.0 97.5 98.0 98.5 99.0 99.5 100.0 100.5 101.0 Body Temperature (degrees Fahrenheit)
