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 56 healthy adults 1 to 4 times daily for 3 days, obtaining 250 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 a=0.01 level of significance. State the hypotheses. Ho H₁: 98.6°F 98.6°F Find the test statistic. to = (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.)
