Question 1192252: In a 1868 paper, German physician Carl Wunderlich reported based on over a million body temperature readings that the mean body temperature for healthy adults is 98.6° F. However, it is now commonly believed that the mean body temperature of a healthy adult is less than what was reported in that paper. To test this hypothesis a researcher measures the following body temperatures from a random sample of healthy adults.
98.2, 98.5, 98.6, 98.5, 97.3, 98.3
(a) Find the value of the test statistic.

The test statistic is a t(df=5)=(x bar-98.6)/s/sqrt (6)
=(98.23-98.6)/0.48/sqrt(6)
=-1.87
