10.3.18-T Question Help My Courses Course Home ? Help 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 98.4°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. Homework (Required) State the hypotheses. Gradebook Ho: Hy: = 98.6°F < 98.6°F StatCrunch Find the test statistic. e Text to = -3.33 (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) Incorrect: 1

Answer 1

With the test statistic t_{​​​​​​0} = -3.33 and df=224,

We have p-value = 0.00050774 $\simeq$ 0.001 ( round to three decimal places).

i.e, p-value = 0.001.
