- In practice, we may trust this test when the number of successes is $10$ or greater and the number of failures is $10$ or greater. That is, when $np_0 \geq 10$ and $n(1 - p_0) \geq 10$.
- When the above guidelines for this test are not met, you may use a non-parametric alternative: Bootstrap Test for a Single Population Proportion.
