Question: it has long been stated that the mean temperature of...

Question details

It has long been stated that the mean temperature of humans is 98.6degrees°F. ​However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6degrees°F. They measured the temperatures of 61 healthy adults 1 to 4 times daily for 3​days, obtaining 275 measurements. The sample data resulted in a sample mean of 98.4degrees°F and a sample standard deviation of 1 degrees°F. Use the​ P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6degrees°F at the alphaαequals=0.01 level of significance.

Find the test statistic.

To=

The​ P-value is=
