The Cheetah's coach tells you that five of his sprinters average 11.5 seconds in the 100 meter dash and that their times have a standard deviation of seconds. He says that his runners' times are normally distributed. The Cheetah's coach also scouted the other team the Rockets. He was able to observe six of their runners. The rockets sprinters had an average time of 11.35 seconds with a standard deviation of 0.2 seconds . The cheetahs' coach believes that the Rockets' times are normally distributed as well.
