It has long been stated that the mean temperature of humans is 98.6degreesF. ​However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6degreesF. 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 98.3degreesF and a sample standard deviation of 1degreesF. Use the​ P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6degreesF at the a=0.01 level of significance.
