This paper proposes a class of exponential type estimator to estimate the population mean in the presence of non-response adapting the estimators suggested by Singh et.al , Kumar and Bhougal , and Rachokarn and Lawson . The general expressions for bias and MSE of the proposed class of estimator have been obtained. In addition, theoretical and numerical studies were used in order to access the performance of proposed class of estimator. The results of this study showed that the proposed class of estimator is always efficient under the percent relative efficiencies (PREs) criterion as compared to other relevant estimators.
