Question

2).

a.
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 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.) A. The baby born in week 41 weighs relatively less since its Z-score, is larger than the z-score of for the baby born in week 35. B. 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 41. C. 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 41. D. The baby born in week 41 weighs relatively less since its z-score, is smaller than the z-score of for the baby born in week 35.
