The histograms below are from 4 sets of 10000 randomly selected tax returns from the IRS. Find the
mean and standard deviation for each set and compare them to Benford’s Law. Consider values that
fall above/below 1.0 standard deviations from the mean and determine whether any set of these tax
returns are suspected to be fraudulent. Discuss how you would convince someone (like a judge)
that they may be fraudulent? Support your argument with calculated values for each graph.
