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 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 v 98.6°F H, v 98.6°F
