13. Suppose your company produces "fat free piza" and your boss feels that the average weight of a case of pizas is 56 pounds. You disagree with your boss. You then take a sample of 45 cases and find the average weight to be 52 pounds with a standard deviation of 9. Note that this sample standard deviation is for raw data and not sample means, even though you are dealing with sample mean data. Assume that your boss is a maniac and you do not want to dispute anything the boss says, unless you are 97% confident. Please utilize the five steps of "hypothesis testing", as done in lecture, and graph your solution. Do you reject or not? 14.
