Question

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 2900 grams and a standard deviation of 370 grams. If a 32-week gestation period baby weighs 2475 grams and a 40​-week gestation period baby weighs 2675 ​grams, find the corresponding​ z-scores. Which baby weighs moremore relative to the gestation​ period? Find the corresponding​ z-scores. Which baby weighs relatively moremore​? Select the correct choice below and fill in the answer boxes to complete your choice. ​(Round to two decimal places as​ needed.)

A. A.The baby born in week 32 weighs relatively less since its​ z-score,   ,is smaller than the​ z-score of    for the baby born in week 40

B.The baby born in week 32 weighs relatively less since its​ z-score, , is larger than the​ z-score of   for the baby born in week 40.

C.The baby born in week 40 weighs relatively less since its​ z-score, , is smaller than the​ z-score of   for the baby born in week 32.

D.The baby born in week 40 weighs relatively less since its​ z-score, ,is larger than the​ z-score of   for the baby born in week 32
