Question 1114939: Assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. Suppose that 700 couples each have a baby; find the mean and standard deviation for the number of boys in the 700 babies. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. Suppose that 700 couples each have a baby; find the mean and standard deviation for the number of boys in the 700 babies.
-------
mean = n*p = 700(1/2) = 350
std = sqrt(n*p*q) = sqrt(350(1/2)(1/2)) = 1/2sqrt(350) = 9.3541
