Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. 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 0.50. Assume that the groups consist of 32 couples.  A) Find the mean and the standard deviation for the numbers of girls in groups of 32 births.
