Problem # 8: A simple random sample of 85 basketball players is taken from different teams and their mean weight is found to be 230 pounds and the standard deviation of the population is 18 pounds. At the significance level of 0.01 test the claim that the average weight for all basketball players is 225 pounds. Use the traditional method of hypothesis testing. Find the critical value(s).
