## Abstract The problem of estimating the common mean of two normal populations __N(ฯ, a1ฯ2__) and __N(ฯ, a2ฯ2__) where the coefficients of variation of two populations respectively, are known constants, on the basis of two independent random samples, one from each population, is considered. The mi
For the estimation of population mean a class of estimators has been proposed when the coefficient of variation is known and its efficiency is compared with the usual unbiased estimator and the estimators suggested by various researchers. The properties of the proposed class of estimators have been
