Does the value of the standard deviation depend on the value of the mean? A) No, because the center of a distribution and the spread are not related. B) Yes, because if the mean gets larger, the standard deviation will also get larger. C) Yes, because the mean must be known in order to calculate the standard deviation.

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 0.50. Assume that the groups consist of 32 couples. A) Find the mean and the standard deviation for the numbers of girls in groups of 32 births.
