Problem $5(10$ pts$)$

In the final inspection of a clock radio production, the Quality Control and Improvement Team tallied the number of occurrences $($frequency$)$ for each defect. They also estimated rework cost for faults which are shown in table below:

$\backslash$table$[[$Defect code,Defect description,Occurrences,Criticality,Weight,Weighted score$],[$A$,$Scratches,$15,$Minor,$10,150],[$B$,$Stains,$17,$Minor,$10,170],[$C$,$Label smudge,$12,$Minor,$10,120],[$D$,$Dent,$14,$Major,$25,350],[$E$,$Device nonfunctional,$5,$Critical,$100,500],[$F$,$Broken LED,$7,$Critical,$100,700],[$G$,$Missing screw,$3,$Major,$25,75]]$

Construct Pareto charts for Final assembly inspection based on frequency of occurrence and based on Weighted score. Please make sure to include the cumulative percentages. Determine the $3$ main defects that need to be addressed and give comments on issues critical to customers based on their Weighted score.
