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 states that the normal approximation is appropriate if both $np \geq 5$ and $n(1-p) \geq 5$. For $n = 50$ and $p = 0.05$, $np = 2.5$, which is less than 5, so the rule is not satisfied.
