A CONFIDENCE INTERVAL FOR PROPORTION IN FINITE POPULATION DIVIDED INTO TWO STRATA: A NUMERICAL STUDY
Consider a finite population of N units. Let θє(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. Suppose, that the population is divided into two (disjoint) strata. In the paper the confidence interval for θ is proposed based on samples from two strata.
