Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2600 grams and a standard deviation of 800 grams while babies born after a gestation period of 40 weeks have a mean weight of 3000 grams and a standard deviation of 485 grams. If a 35-week gestation period baby weighs 2350 grams and a 41-week gestation period baby weighs 2750 grams, find the corresponding Z-scores. Which baby weighs less relative to...
