Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 700 grams while babies born after a gestation period of 40 weeks have a mean weight of 2800 grams and a standard deviation of 465 grams. If a 34-week gestation period baby weighs 2225 grams and a 40-week gestation period baby weighs 2525 grams, find the corresponding z-scores. Which baby weighs less relative to the gestation period?
