What’s Normal II
Of the 130 people in Exercise, 65 were female and 65 were male.3 The means and standard deviations of their temperatures are shown below.

a. Use the p-value approach to test for a significant difference in the average temperatures for males versus females.

b. Are the results significant at the 5% level? At the 1% level?

Exercise:

What’s Normal?
What is normal, when it comes to people’s body temperatures? A random sample of 130 human body temperatures, provided by Allen Shoemaker³
in the Journal of Statistical Education, had a mean of 98.25 degrees and a standard deviation of 0.73 degrees. Does the data indicate that the average body temperature for healthy humans is different from 98.6 degrees, the usual average temperature cited by physicians and others? Test using both methods given in this section.
