The average body temperature of humans is believed to be 98.6°F with a standard deviation of 0.9°F. You randomly test the body temperature of 19 individuals and find the mean body temperature is 98.9°F. Is the mean body temperature of humans equal to 98.6°F? Assume that human body temperature is normally distributed. What is the decision for this hypothesis test? Fail to reject the null because the test statistic is not in the rejection region and the p-value is less than a. Reject the null because the test statistic is in the rejection region and the p-value is less than a. Fail to reject the null because the test statistic is in the rejection region and the p-value is greater than a. Reject the null because the test statistic is in the rejection region and the p-value is greater than a. Fail to reject the null because the test statistic is not in the rejection region and the p-value is greater than a.
