A sample is large if the interval [ p − 3 σ p ^, p + 3 σ p ^] lies wholly within the interval [ 0, 1]. In actual practice the value of p is not known, hence neither is σ p ^. In that case we substitute the known quantity p ^ for p in making ...

WebNow look, we can take the number of successes/ failures to find the proportion of successes/failures in the sample: 20/50= 0.4. 0.4=p. 30/50=0.6. 0.6= 1-p. So essentially, we need to first check that the sample size is larger than 30. And if that is met, then we check if the number of successes/ failures in a sample are more than 10.
