As a general rule, the normal distribution is used to approximate the sampling distribution of the sample proportion only if both n * $\hat { p }$ and n * $\hat { q }$ are at least five ( $\hat { q }$ = 1 - $\hat { p }$ ).

This statement is true. The normal distribution can be used to approximate the sampling distribution of the sample proportion if both n$\hat{p}$ and n$\hat{q}$ are at least 5. This is known as the "success-failure" rule, where at least 5 successes and 5 failures are required for an accurate approximation.
