This paper introduces an estimator of population mean Y of the study variable y using auxiliary variable x in stratified random sampling. The bias and variance of the proposed estimator have been derived under large sample approximation. Asymptotic optimum estimator (AOE) is identified with its approximate variance formula. Estimator based on " estimated(More)
