Abstract :This paper proposes new exponential estimators combining ratio estimators for estimate population mean of study variable using information about population proportion possessing certain attributes. It is obtained mean square error (MSE) equations for all proposed ratio exponential estimators and is shown that all proposed exponential estimators are always more efficient than the ratio estimators. In addition, these results are supported by an application with original data sets.
