For a one-sample test for a population proportion p and sample size n, why is it necessary that np0 and n(1−p0) are both at leas

tino4ka555 [31]

Using the Central Limit Theorem, it is found that these conditions are required to avoid the high variability associated with small samples.

<h3>What does the Central Limit Theorem states?</h3>

It states that for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportion is approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1 - p)}{n}}$ , as long as $np \geq 10$ and $n(1 - p) \geq 10$ .

From the equation of the standard error, we could see that if one of the conditions is not respected, the standard error would be very high, indicating a low accuracy of the estimate, hence it is found that these conditions are required to avoid the high variability associated with small samples.
