In this paper, we have proposed an estimator of finite population mean using a new regression
type estimator with two auxiliary variables for single-phase sampling and investigated its finite
sample properties. An empirical study has been carried out to compare the performance of the
proposed estimator with the existing estimators that utilize auxiliary variables for finite population
mean. It has been found that the new regression type estimator with two auxiliary variables
for to be more efficient than mean per unit, ratio and product estimator and exponential ratio and
exponential product estimators and exponential ratio-product estimator
