• If you haven't done so already (in conjunction with Problem 17-70), prepare in Excel a cost-of-quality (COQ) report for 2019 and 2020. Show subtotals each year for each of the four COQ categories. As well, show category costs each year as a percentage of revenue for the year. Finally, show each year total COQ as a percentage of revenue for the year. and set up a spreadsheet for this information. Round all percentages to 2 decimal places.

4. Move to another area of your spreadsheet and title the area "Cost of QualityTrend Analysis." Show, for both 2019 and 2020, COQ spending (both category-level and in total) as a percentage of sales for the year. Show all percentages to 2 decimal places.
6. Provide a bar chart to compare the percentages of each of the COQ categories and the total COQ for 2020 vs. 2019.
8. Complete a sensitivity analysis by making the following (joint) changes to the 2020 amounts:
   2. Increase the total sales by 5%.
   4. Increase total prevention cost by 6%.
   6. Decrease total internal failure cost by 60%.
   8. Decrease total external failure cost by 50%.

For each of the four COQ categories, what is the revised (i.e, 2020) category cost as a percentage of sales, rounded to 2 decimal places?
