Problem IV Frank, the older of two brothers, weighs 120 lbs. Joe, the younger of the two brothers, weighs 90 lbs. 1. If the two brothers sit at opposite ends of a 21 foot long teeter-totter, how far from Frank should the fulcrum of the teeter-totter be located so that the weights of the two brothers are balanced? Suppose the mean and standard deviation of weight for boys Frank's age are 100 lbs and 15 lbs. Suppose the mean and standard deviation of weight for boys Joe's age are 75 lbs and 10 lbs. 2. What is Frank's z-score relative to the population of boys his age? 3. What is Joe's z-score relative to the population of boys his age? 4. Which boy is heavier relative to boys of their own age?
