Transcribed Image Text: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.
