Sample Size Comparisons Involving the Randomized Response Technique.

Abstract: The purpose of the present paper is to demonstrate how many more subjects are required to achieve equal power when testing certain hypotheses concerning proportions if the randomized response technique is employed for estimating a population proportion instead of the conventional technique.
