Abstract: In this paper, we explore a new estimation technique for estimating variance of the conventional product estimator under simple random sampling assuming that the population mean and population variance of the auxiliary variable are known prior to sampling. Accordingly, we formulate some new variance estimators under classical as well as predictive approach. We test capabilities of our estimators empirically by means of a simulation study in respect of bias, efficiency, coverage rate based on 95% confidence interval and stability.
