Recall the rule of thumb used to indicate when the normal distribution is a good approximation to the sampling distribution for the sample proportion $\hat { p }$ . For the combination n = 50; p = 0.05, the rule is satisfied.

The rule of thumb for the normal approximation to be considered good is that both $np$ and $n(1-p)$ should be greater than or equal to 10. For $n = 50$ and $p = 0.05$, $np = 2.5$ and $n(1-p) = 47.5$, so the condition is not satisfied because $np < 10$.
