The article "Variance Reduction Techniques: Experimental Comparison and Analysis for Single Systems" (I. Sabuncuoglu, M. Fadiloglu, and S. IIE Transactions, 2008:538-551) describes a study of methods for reducing variance in estimators of the mean inventory on hand for a standard inventory model. Ten replications of an experiment using the method of antithetic variates yielded an average reduction of 10.7% with a standard deviation of 4.1%. Can you conclude that the mean reduction for this method is greater than 10%?
