What is normal when it comes to people’s body temperatures? A random sample of 130 human body temperatures provided by Allen Shoemaker in the Journal of Statistical Education had a mean of 36.810 Celsius and a standard deviation of 0.730 . Do the data indicate that the average body temperature for healthy humans is different from 37.0 , the usual average temperature cited by physicians and others? Test using the following three methods. (a) Use the critical value approach with ? = 0.05 (b) Use the P-value approach with ? = 0.05 (c) Calculate the 95% confidence interval for the population average body temperature and test the hypothesis. Is the decision same as p-value or critical value approach?
