Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2,700 grams and a standard deviation of 900 grams, while babies born after a gestation period of 40 weeks have a mean weight of 3,000 grams and a standard deviation of 465 grams. If a 33-week gestation period baby weighs 2,225 grams and a 40-week gestation period baby weighs 2,525 grams, find the corresponding z-scores. Which baby weighs less relative to the gestation period? a. The 33-week gestation period baby weighs standard deviations the mean.
b. The 40-week gestation period baby weighs standard deviations the mean.
(Round to two decimal places as needed.)
c. Which baby weighs relatively less?
A. The baby born in week 40 does since its z-score is smaller.
B. The baby born in week 40 does since its z-score is larger.
C. The baby born in week 33 does since its z-score is larger.
D. The baby born in week 33 does since its z-score is smaller.
