Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 700 grams while babies born after a gestation period of 40 weeks have a mean weight of 2900 grams and a standard deviation of 475 grams. If a 32-week gestation period baby weighs 2250 grams and a 40-week gestation period baby weighs grams, find the corresponding z-scores. Which baby weighs less relative to the gestation period?
