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 healthy adults at different times of day obtaining 225 measurements. The sample data resulted in a sample mean of 98.4°F and a sample standard deviation of 1.1°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.)
What can be concluded? O A. Reject Ho since the P-value is not less than the significance level. O B. Do not reject Ho since the P-value is not less than the significance level. OC. Do not reject Ho since the P-value is less than the significance level. O D. Reject Ho since the P-value is less than the significance level.
