Subramani & G. Kumarapandiyan [American Journal of Matematics and Statistics, 2(5): 101-107]. The estimators are biased estimators and the mean square errors are determined. Estimator with the smallest mean square error is the most efficient estimator. A numerical example is given at the end of discusssion.othersimple random samplinglinear combinationmediancoefficient of skewnessmean square errorOther
