Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 600 grams while babies born after a gestation period of 40 weeks have a mean weight 3300 grams and a standard deviation of 455 grams. If a 35week gestation period baby weighs 3125 grams and a 40 week gestation period baby weighs 3625 grams. Find the corresponding z-score. Which baby weighs more relative to the gestation period?
The 35-week gestation period baby weighs __standard deviations (above or below) the mean?
The 40-week gestation period baby weighs __ standard deviations (above or below) the mean?
Which baby weighs relatively less?
The baby born in week 35 does since itsz-score is smaller.
The baby born in week 40 does since itsz-score is smaller.
The baby born in week 35 does since itsz-score is larger.
The baby born in week 40 does since itsz-score is larger.
