In order to conduct a one-sample proportion z-test, the following conditions should be met:
- The data are a simple random sample from the population of interest.
- The population is at least 10 times as large as the sample.
n*p>=10n⋅p≥10 andn*(1-p)>=10n⋅(1−p)≥10 , wherenn is the sample size andpp is the true population proportion.
