This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect, so the probability of a girl is 0.5. Assume that the groups consist of 24 couples. Complete parts (a) through (c) below. E a. Find the mean and the standard deviation for the numbers of girls in groups of 24 births. The value of the mean is p = I: (Type an integer or a decimal.
