Consider the following data from the automobile industry (adapted from Kane 1989). All cars produced on a particular day were inspected for defects. The 145 defects found were categorized by type as shown in the accompanying table.

a. Construct a Pareto diagram for the data. Use the graph to identify the most frequently observed type of defect.
b. All 70 car body defects were further classified as to type. The frequencies are provided in the following table. Form a Pareto diagram for type of body defect. (Adding this graph to the original Pareto diagram of part a is called exploding the Pareto diagram. Interpret the result. What type of body defect should be targeted for special attention?
