Consider a finite population of N units. 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 re¬pla¬ce¬ment. It is of interest to obtain confidence intervals of a prescribed length. In the paper the minimal sample size which guarantees the length to not exceed the given value is calculated.
