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 27 couples. Complete parts (a) through (c) below.(a) Find the mean and the standard deviation for the numbers of girls in groups of 48 births.(b) Use the range rule of thumb to find the values separating results that are significantly low or significantly high.(c) Is the result of 42 girls a result that is significantly high? What does it suggest about the effectiveness of the method?
