Question

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2600 grams and a standard deviation of 700 grams while babies born after a gestation period of 40 weeks have a mean weight of 2900 grams and a standard deviation of 430 grams. If a 34-week gestation period baby weighs 2850 grams and a 40-week gestation period baby weighs 3150 grams, find the corresponding z-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more? 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 34 weighs relatively more since its Z-score, is larger than the Z-score of for the baby born in week 40. B. The baby born in week 34 weighs relatively more since its Z-score, is smaller than the Z-score of for the baby born in week 40. OC. The baby born in week 40 weighs relatively more since its z-score, is smaller than the Z-score of for the baby born in week 34. D. The baby born in week 40 weighs relatively more since its z-score, is larger than the Z-score of for the baby born in week 34.
