A Note on Estimation of Population Mean in Sample Survey using Auxiliary Information

In this paper we have suggested a class of estimators for population mean using auxiliary information in two-phase sampling. When the population mean  is not known, a class of estimators for finite population mean  of the study variable y has been suggested. Expressions of bias and mean squared error are obtained upto the first order of approximation. Asymptotically optimum estimators (AOE’s) are also identified with its mean squared error formula. We found that proposed class of estimator are better than usual ratio and other estimators
