It is commonly presumed that an unborn child has a 50% prob ability of being female. But is this really the case? Let's take a look at birth statistics for the Netherlands for the years 1989. 1990, and 1991. According to the Central Bureau of Statistics, there were, in total, 585,609 children bom during the span of those years, of which 286,114 were girls. What is the esti mate for the probability that a newborn child will be a girl and what is the corresponding 95% confidence interval?
