Pareto Chart

Not sure how to complete this task. Need help and direction.

The Wellington Fiber Board Company produces headliners, the fiberglass components that form the inner roof of passenger cars. Of late, they have noticed a growing number of defects in their product. To get a handle on the problem, they have made an analysis of the 50 most recent defects, with results as follows:
Type of Defect Number of Defects

A. Tears in fabric 4
B. Discolored fabric 3
C. Broken fiber board 36
D. Ragged edges 7

? Prepare a Pareto Chart for the defect experience.
? This is a 3 shift operation. 10 of the C type defects occurred on the first shift, 20 on the second, the remainder on third shift. Any conclusions from this data?
? In terms of a Cause and Effect diagram, what may be the functional causes for the problems related to broken fiber boards? Construct a Cause and Effect diagram.
