The sample size needed to estimate the difference between two population proportions to within a margin of error $E$ with a confidence level of $1-\alpha$ can be found by using the following expression:

$$E=z_{\alpha / 2} \sqrt{\frac{p_1 q_1}{n_1}+\frac{p_2 q_2}{n_2}}$$

Replace $n_1$ and $n_2$ by $n$ in the formula above (assuming that both samples have the same size) and replace each of $p_1, q_1, p_2$, and $q_2$ by $0.5$ (because their values are not known). Solving for $n$ results in this expression:

$$n=\frac{z_{a / 2}^2}{2 E^2}$$

Use this expression to find the size of each sample if you want to estimate the difference between the proportions of adult men and women who are college graduates. Assume that you want $90 \%$ confidence that your error is no more than $0.02$.
