Ch12) 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 44 healthy adults 1 to 4 times daily for 3 days, obtaining 200 measurements. The sample data resulted in a sample mean of 98.4°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 H₁ 98.6°F Find the test statistic. 1- (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) What can be concluded? OA. Reject Ho since the P-value is less than the significance level. OB. 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. Relect He since the P-value is not less than the significance level.

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 44 healthy adults 1 to 4 times daily for 3 days, obtaining 200 measurements. The sample data resulted in a sample mean of 98.4°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
H₁
98.6°F
Find the test statistic.
1-
(Round to two decimal places as needed.)
The P-value is
(Round to three decimal places as needed.)
What can be concluded?
OA. Reject Ho since the P-value is less than the significance level.
OB. 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.
Relect He since the P-value is not less than the significance level.
