Some studies show that the mean normal human body temperature is actually somewhat lower than the commonly given value of 37C. This is reflected in the following data set of body temperatures. Body temperatures (C) of 30 healthy adults are recorded as follows:

36.1 37.2 37.0 37.3 36.9 36.5 37.8 35.9 36.3 37.2

37.0 37.2 36.8 37.5 37.3 36.7 36.8 37.7 37.2 36.5

36.1 36.5 36.7 37.1 37.2 36.6 36.4 36.6

36.7 37.8
