In the Neyman-Pearson Theory the notion of least favorable mixture provides a reduction of a composite null hypothesis to a simple one that is equivalent for finding a most powerful test against a simple alternative. The aim of this paper is to prove a property of mixtures from which follows Lehmann-Stein Theorem (1948) connecting least favorable mixtures with most powerful tests. As application classical χ2 test for the variance of a Normal distribution with unknown mean is considered. Keywords: Most Powerful Test, Neyman-Pearson Theory, Least Favorable Mixture.
