Applied Statistics and Probability for Engineers 9-75. Human oral normal body temperature is believed to be
98.6° F, but there is evidence that it actually should be 98.2° F
[Mackowiak, Wasserman, Steven and Levine, JAMA (1992, Vol.
268(12), pp. 1578–1580)]. From a sample of 52 healthy adults,
the mean oral temperature was 98.285 with a standard deviation
of 0.625 degrees.
