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 50 healthy adults 1 to 4 times daily for 3 days, obtaining 225 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 H1 < 98.6°F Find the test statistic to =-0 41 (Round to two decimal places as needed) The P-value is 341 (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 2 O B. Do not reiect Hn since the P-value is less than the sianificance 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 50 healthy adults 1 to 4 times daily for 3 days, obtaining 225 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
H1:
< 98.6°F
Find the test statistic.
to :
-0.41
(Round to two decimal places as needed.)
The P-value is 341
(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.
B. Do not reject Hn since the P-value is less than the significance level.
