The variance expressions of the suggested estimators have been obtained and compared with usual unbiased estimator y*, Swain's (1964) ratio estimator y*R and Shukla's product estimator y*p. It has been shown that the proposed estimators are more efficient than usual unbiased estimator y*, ratio estimator y*R and product estimator y*p. An empirical study is carried out to demonstrate the superioriy of the constructed estimators over the estimators y*, y*R and y*p.
