The USGA specifications for golf balls is that a ball must weigh no more than 1.62 oz. The manufacturing process for one company’s golf balls produces a normally distributed distribution of ball weights. To determine if a lot of golf balls produces acceptable balls, a random sample of 25 balls is selected from each lot and tested. One particular lot has a mean weight of 1.625 oz with a standard deviation of .011 oz. Create a 99% confidence interval for the actual weight of a golf ball. Using this interval, is the company making acceptable balls? Explain your answer.
