Monte Carlo simulation results on confidence interval coverage of the gamma estimator (arithmetic mean) with lognormaliy distributed data, EX=1. Values. at the intersections of rows and columns are the proportion of 1000 replicates where the computed confidence interval included the true expected value. 623
