Some ratio estimators for estimating the population mean of the variableunder study, which make use of information regarding the population proportionpossessing certain attribute, are proposed. Under simple random samplingwithout replacement (SRSWOR) scheme, the expressions of bias and mean-squarederror (MSE) up to the first order of approximation are derived. The resultsobtained have been illustrated numerically by taking some empirical populationconsidered in the literature.
