In this model, we want to come up with a sampling strategy that yields a variance within a specified target at minimal cost. We have four strata of a population we will be querying on two topics. There is a maximum variance limit on each of the two questions. We know the variance in responses for each stratum on each question. How many respondents must you select from each stratum to meet your maximal variance requirements at minimal cost?
