Question

It has long been stated that the mean temperature of humans is 98.6 degrees°F. ​However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degrees°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 degrees°F and a sample standard deviation of 11 degrees°F. Use the​ P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6 degrees°F at the α = 0.01 level of significance.

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 1 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 α = 0.01 level of significance. 13. State the hypotheses. (2) 98.6℉ H: (3) 98.6°F Find the test statistic. (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.
