Suppose babies born after a gestation period of 32 to 35 weeks have a mean weigh

Question

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2900 grams and a standard deviation of 700 grams while babies born after a gestation period of 40 weeks have a mean weight of 3200 grams gestation and a standard deviation of 450 grams. If a 34 week gestation period baby weighs 3250 gram s and a 40-week gestation period baby weighs 3550 grams, find the corresponding z-scores which baby weighs more relative to the gestation period? The 34-week gestation period baby weighs standard deviations the mean The 40-week gestation period baby weigh standard deviation. the mean

Explanation / Answer

Z score for 34 week baby = (3250-2900)/700 = 0.5

Z score for 40 week baby = (3550-3200)/450 = 0.78

The 34 week gestation period babuly weighs 0.5 standard deviation above the mean.

The 40 week gestation period baby weighs 0.77 standard deviation above the mean.

40 week baby weight more relative to the gestation period.
