This document discusses conditions for determining whether the sampling distribution of a population proportion (p) can be approximated as normal. It provides examples checking the conditions of np, n(1-p), and sample size (n) being greater than 30 for populations with different percentages of a disease (p=2% and p=90%) and different sample sizes (n=44, 542). It also discusses a case where the population size is less than the sample size. The last question notes that the previous section established a sample size of 30 or more is enough to use the normal distribution, while these problems deal with quantitative rather than qualitative variable information.
