Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 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 455 grams. If a 35-week gestation period baby weighs 2325 grams and a
40-week gestation period baby weighs 2925 grams, find the corresponding Z-scores. Which baby weighs less relative to the gestation period?
Find the corresponding Z-scores. Which baby weighs relatively less? Select the correct choice below and fill in the answer boxes to complete your choice.
(Round to two decimal places as needed.)
O A. The baby born in week 35 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 40 weighs relatively less since its Z-score, is larger than the Z-score of for the baby born in week 35.
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 35.
D. The baby born in week 35 weighs relatively less since its z-score, is larger than the Z-score of for the baby born in week 40.
