The present work endeavors to propose some classes of exponential-type estimators to estimate population mean of a sensitive character using a non-sensitive auxiliary information in two move successive sampling. To deal with sensitive issues, randomized response techniques have been applied. The detail properties of the proposed classes of estimators have been discussed. They are also compared with some recent estimators which have been modified to work for sensitive population mean estimation. Extensive numerical illustrations along with simulation studies have been carried out to substantiate the theoretical results. Optimum replacement policies have also been elaborated. Finally appropriate recommendations have been forwarded for practical applications.
