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.)

The weights of rabbits on an island, measured in pounds, are normally distributed with mean 4.5 and standard deviation 3.1. In each case, identify the calculator command that would answer the given question. The chances that a randomly selected rabbit weighs at least 6 pounds. The chances that 15 randomly selected rabbits have an average weight of at least 6 pounds. The chances that 15 randomly selected rabbits have a total weight less than 50 pounds.
