## Abstract The problem of estimating the common mean of two normal populations __N(ฯ•, a1ฯ•2__) and __N(ฯ•, a2ฯ•2__) 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.

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
