For Lab today Prof. Conquest had the class take replicates of samples of size 5 from a Uniform distribution.  This was accomplished by having each student use Table B.41 to choose a block of five random digits.  Each student then summed the digits and divided by 5 to get a mean for that block.  We then created a histogram of those means.
