\fReq 1 Req 2A Reg 23 Reg 3A Req 4 Using the classifications in requirement 1, compute AT's prevention, appraisal, internal failure, and external failure costs as a percentage of total quality costs. (Round "Percentage of Total Quality Costs'1 to 2 decimal places. Total may not be equal to 100% due to rounding.) Preve ntion Appraisal Internal failure External failure \fAdvanced Technologies (AT) produces two compression machines that are popular with manufacturers of plastics: no. 165 and no. 172. Machine no. 165 has an average selling price of $30,600, whereas no. 172 typically sells for approximately $28,100. The company is very concerned about quality and has provided the following information: No. 165 No. 172 Number of machines produced and sold 188 228 Warranty costs: Average repair cost per unit $ 938 $ 368 Percentage of units needing repair 68% 18% Reliability engineering at $188 per hour 1,615 hours 2,838 hours Rework at AT's manufacturing plant: Average rework cost per unit $ 1,938 $ 1,618 Percentage of units needing rework 48% 28% Manufacturing inspection at $d8 per hour 315 hours 518 hours Transportation costs to customer sites to tix problems $29,888 $15,688 Quality training for employees $35,688 $58,388 Required: 1. Classify the preceding costs as prevention, appraisal, internal failure, or external failure. 2-a. Using the classifications in requirement 1, compute AT's quality costs for machine no. 165 in dollars and as a percentage of sales revenues. 2-b. Using the classications in requirement 1, compute AT's prevention, appraisal, internal failure, and external failure costs as a percentage of total quality costs. 3-a. Using the classications in requirement 1, compute AT's quality costs for machine no. 172 in dollars and as a percentage of sales revenues. 3-b. Using the classifications in requirement 1. compute AT's prevention, appraisal, internal failure, and external failure costs as a percentage of total quality costs. 4. Is the company "investing" its quality expenditures differently for the two machines?
