Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2900 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3500 grams and a standard deviation of 570 grams. If a ​33-week gestation period baby weighs 2475 grams and a 40​-week gestation period baby weighs 3075 ​grams, find the corresponding​ z-scores. Which baby weighs relative to the gestation​ period?
