How many infants with at least one birth defect would we expect among the 837 ivf infants if the true prevalence of at least one birth defect in the ivf group were the same as for infants conceived naturally?

According to the CDC, Central for Disease Control, 1 and 33 infants are born each year with a brith defect.  If the the rate for a least one birth defect for ivf infants is the same as infants conceived naturally then, in a group of 837 ivf infants there would be about 25 infants born with birth defects.


That answer was found by dividing 837 by 33.

837/33= 25.364

Since 0.364 is not a whole number we round to the nearest whole number, 25.

Answer: 25 Infants
