You can use the Alternative Scenarios to see how changing the four inputs the margin of error confidence level population size and sample proportion affect the sample size. This means that if there are 2 boys in this class then there are 5 girls. Q 1 p The variable p has a binomial distribution that can be approximated with the normal distribution shown here. The variable p is the sample proportion and serves as the point estimate for the true population proportion.
