We аre interested in estimаting the аverage driving time оf students whо cоmmute to Ohio State. From data sampled previously, we believe that the longest driving time is 66 minutes and the shortest driving time is 18 minutes. How many students who commute need to be included in our sample to order to be 98% confident that the estimated mean driving time will be within 4 minutes of the true population mean driving time?
