il Homework: Homework Section 3.4 Score: 0 of 1 pt HW Score: 25%, 2 of 8 pts 3.4.5 Help Suppose bables born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 310 40-week gestation period baby weighs 2850 grams, find the 0 grams and a standard deviation of 430 grams. If a 35-week gestation period baby weighs 2450 grams and a g z-scores. Which baby weighs less relative to the gestation period? The 35-week gestation period baby waighs standard deviations below the mean The 40-week gestation period baby weighs standard deviations below the mean Round to two decimal places as needed)Explanation / Answer
as we know z score =(X-mean)/std deviation
the 35 week gestation period baby weight (2700-2450)/900=0.28 standard deviation below the mean
the 40 week gestation period baby weight (3100-2850)/430=0.58 standard deviation below the mean
