In an article in the Journal of Statistics Education (vol. 4, no. 2). Allen Shoemaker describes a study that was reported in the Journal of the American Medical Association (JAMA). It is generally accepted that the mean body temperature of an adult human is 98.6F. In his article, Shoemaker uses the data from the JAMA article to test this hypothesis. Here is a summary of his test.
