The article "Variance Reduction Techniques: Experimental Comparison and Analysis for Single Systems" (1. Sabuncuoglu, M. Fadiioglu. and S. Celik, HE Transactions, 2008:538-551) describes a study of the effectiveness of the method of Latin Hypercube Sampling in reducing the variance of estimators of the mean time-in- system for queueing models. For the M/M/l queueing model, ten replications of the experiment yielded an average reduction of 6.1 with a standard deviation of 4.1. For the serial line model, ten replications yielded an average reduction of 6.6 with a standard deviation of 4.3. Can you conclude that the mean reductions differ between the two models?
