When testing a method of gender selection prior to childbirth, we assume that the rate of female births is 50%, and we reject that assumption if we get results that are unusual in the sense that they are very unlikely to occur with a normal 50% birth rate. Assuming a 50% rate of female births, find the standard deviation of the number of girls in 15 births.
