We propose a class of estimators for the unknown mean of a survey variable, when auxiliary information is available. The bias and the mean square error of the estimators belonging to the class are obtained and the expression for the optimum value minimizing the asymptotic mean square error is given. Conditions for the proposed class of estimators to be more efficient than the other estimators are investigated. An empirical study is carried out to show the performance of the proposed estimator over others.
