Researchers measured the waist sizes of 251 men in a study on body fat. The true mean and standard deviation of the waist sizes for the 251 men are 36.426 inches and 4.129 inches, respectively. To explore variation of the mean from sample to sample, they simulated by drawing many samples of size 2, 5, 10, and 20 with replacement, from the 251 measurements. The histograms and summary statistics for each simulation are shown in the accompanying table. - X n Mean st. dev.
