Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 800 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 470 grams. If a 35-week gestation period baby weighs 2625 grams and a 41-week gestation period baby weighs 2925 grams, find the corresponding z-scores. Which baby weighs less relative to the gestation period?
