Assume that different groups of couples use a particular method of genderselection and each couple gives birth to one baby. This method is designed toincrease the likelihood that each baby will be a girl, but assume that the methodhas no effect, so the probability of a girl is 0.5. Assume that the groups consist of34 couples. Complete parts (a) through (c) below....a. Find the mean and the standard deviation for the numbers of girls in groups of34 births.The value of the mean is µ =0.(Type an integer or a decimal. Do not round.)
