Question

It has long been stated that the mean temperature of humans is 98 6 degree F However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degree F. They measured the temperatures of 148 healthy adults 1 to 4 times daily for 3 days, obtaining 600 measurements The sample data resulted in a sample mean of 97.9 degree F and a sample standard deviation of 0.7 degree F Using the classical approach, judge whether the mean temperature of humans is less than 98.6 degree F at the alpha= 0.01 level of significance Approximate the P-value Click here to view the t-Distribution Area in Right Tal. Choose the correct answer below, Reject H_o since the test statistic is less than the critical value. Do not reject H_o since the test statistic is less than the critical value, Reject H_o since the test statistic is not less than the critical value, Do not reject H_o since the test statistic is not less than the critical value, The P-value is approximately (Round to four decimal places as needed) Enter your answer in the answer box and then click Check Answer

Explanation / Answer

value of test statistics
t = (97.9 - 98.6)/(0.7/sqrt(600)) = -24.495

degrees of freedom = 600 - 1 = 599

p-value = 0.0000
