We calculated a vector errors that contained, for each simulated sample, the difference between the actual value \(p\) and our estimate \(\hat{X}\).

The errors \(\bar{X} - p\) are:

practically equal to 0.

approximately normal with expected value \(0\) and standard error \(\sqrt{p(1-p)/N}\).

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

not a random variable.
