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 600 grams while babies born after a gestation period of 40 weeks have a mean weight of 3000 grams and a standard deviation of 470. If a 32-week gestation period baby weighs 2200 grams and a 40-week gestation period baby weighs 2500 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 32 weighs relatively less since its z-score, _____, is larger 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 smaller than the z-score of negative ________ for the baby born in week 32.

C. 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.
