[Show abstract][Hide abstract] ABSTRACT: This paper proposes some estimators for the population mean by adapting the estimator in Singh et al. (2008)  to the ratio estimators presented in Kadilar and Cingi 2006 . We obtain mean square error (MSE) equation for all proposed estimators, and show that all proposed estimators are always more efficient than ratio estimator in Naik and Gupta (1996) , and Singh et al. (2008) . The results have been illustrated numerically by taking some empirical population considered in the literature.
