Modified Ratio Estimators for Population Mean Using Size of the Sample, selected from Population

Authors(2) :-Mohmmad Jerajuddin, Jai Kishun

This paper deals with a modified ratio estimator for the estimation of population mean of study variable using the size of the sample, selected from the population under SRSWOR. The bias and mean square error of the proposed estimator up to the first order of approximation is derived [Appendix]. The constants, biases and mean square errors (MSEs) are computed using the data from Murthy [1] and Mukhopadhyay [3]. The percent relative efficiencies (PREs) are also computed for both existed and proposed estimators and compare the results accordingly for justifying the betterment of the proposed estimators over other mentioned modified estimators.
