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 44 healthy adults 1 to 4 times daily for 3 days, obtaining 200 measurements The sample data resulted in a sample mean of 982°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.
