For \(N=100\), the central limit theorem tells us that the distribution of \(\hat{X}\) is...

practically equal to \(p\).

approximately normal with expected value \(p\) and standard error \(\sqrt{p(1-p)/N}\).

approximately normal with expected value \(\bar{X}\) and standard error \(\sqrt{\bar{X}(1-\bar{X})/N}\).

not a random variable.
