Let θ ∈(0,1) denotes the fraction of units with a given property. The problem is in interval estimation of θ on the basis of a sample drawn due to the simple random sampling without replacement. In the paper three confidence intervals are compared: exact based on hypergeometric distribution and two other based on approximations to hypergeometric distribution: Binomial and Normal. It appeared that Binomial based confidence interval is too conservative while the Normal based one does not keep the prescribed confidence level}, number={1}, journal={Metody Ilościowe w Badaniach Ekonomicznych}, author={Zieliński, Wojciech}, year={2011}, month={grudz.}, pages={177–182} }
