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>=10# and#n*(1-p)>=10# , where#n# is the sample size and#p# is the true population proportion.
