In this paper, we show that the new concept for tuning design weights in survey sampling developed by Singh, Sedory, Rueda, Arcos and Arnab (2015: Elsevier) leads to an innovative Tuned Ratio Unbiased Mean Predictor (TRUMP) with the assistance of a model. It is shown theoretically that the proposed TRUMP is more efficient than the ratio estimator due to Cochran (1940). Although there is no need of empirical investigations, but a small scale simulation study will be discussed. The proposed TRUMP has potential to be extended to the regression predictor and other complex survey sampling designs.
