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.

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 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.
Họ: H
= 98.6°F
H: H < 98.6°F
Find the test statistic.
6-0
(Round to two decimal places as needed.)
The P-value is
(Round to three decimal places as needed.)
What can be concluded?
What can be concluded?
A. Reject Ho since the P-value is not less than the significance level.
B. Reject Ho since the P-value is less than the significance level.
C. Do not reject Ho since the P-value is not less than the significance level.
OD. Do not reject Ho since the P-value is less than the significance level.
