Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. The 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 20 couples. Complete parts (a) through (c) below. Pay attention to the rounding instructions on each problem below. a. Find the mean and the standard deviation for the numbers of girls in groups of 20 births. (Hint: binomial) The value of the mean (or the expected number of girls) is µ =. G (Type an integer or a decimal. Do not round.) A The value of the standard deviation is o = (Round to one decimal place as needed.) Enter your answer in each of the answer boxes. Muitimeata LIDrary
