George has an average bowling score of 180 and bowls in a league where the average for all bowlers is 150 and the standard deviation is 20. Bill has an average bowling score of 190 and bowls in a league where the average is 160 and the standard deviation is 15. Who ranks higher in his own league, George or Bill? George because his standard score is higher than Bill's. Bill because his standard score is higher than George's. George because the standard deviation in his league is higher than the standard deviation in Bill's league. Bill because his 190 is higher than George's 180. Bill and George have the same rank in their leagues because both are 30 pins above the mean
