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 67 healthy adults 1 to 4 times daily for 3 days, obtaining 300 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 98.6 F Hy : 98.6 F Find the test statistic. to =0 (Round to two decimal places as needed.) The P-value is. (Round to three decimal places as needed.) What can be concluded? O A. Do not reject Ho since the P-value is not less than the significance levelf O B. Do not reject Ho since the P-value is less than the significance level. O C. Reject Ho since the P-value is less than the significance level. O D. Reject Ho since the P-value is not less than the significance level
