Question
It has long been stated that the mean temperature of humans is 98.6°F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6°F. They measured the temperatures of 50
healthy adults 1 to 4 times daily for 3 days, obtaining 225 measurements. The sample data resulted in a sample mean of 98.3°F and a sample standard deviation of 0.9°F. Use the P-value approach to conduct a hypothesis test to judge
whether the mean temperature of humans is less than 98.6°F at the a = 0.01 level of significance.
State the hypotheses.
Ho: H
= 98.6°F
H,: H
< 98.6°F
Find the test statistic,
to =
