Help Please!!! 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 0.5. Assume that the groups consist of 41 couples.
Find the mean and the standard deviation for the numbers of girls in groups of 41 births.
