Selwitchka (1980) presents data on 10 types of errors using two measures-frequency and cost:

Note that the first two columns present a Pareto analysis based on frequency of occurrence. Prepare a second Pareto table based on cost. Comment on the ranking of errors using frequency versus ranking based on cost.
