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 98.2°F and a sample standard deviation of 0.9°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. H₂: ▼98.6°F H₁: 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.) What can be concluded? O A. Do not reject Ho since the P-value not less than the significance level.

Question
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 98.2°F and a sample standard deviation of 0.9°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 x = 0.01 level of significance.
State the hypotheses.
98.6°F
Ho: ▼
H₁:
▼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. Do not reject Ho since the P-value is not less than the significance level.
