1. The final inspection for a car engine is used to check for visual defects. The three defects that occur on this product most frequently are paint runs, improper label alignment, and mis-stamped serial number. An uvestigation by an engineer into the reason behind the high defect rate begun, with samples collected every day for 25 days. The results are shown in the following table Mis Number of stamped engines Paint Misaligned serial SAMPLE examined label 100 0 2 1 100 2 2 runs no 4 5 1 2 3 + 3 5 4 7 88888888 5 3 3 3 7 1 3 3 1 2 3 3 2 S $ 9 1 2 10 2 1 3 + 8 3 1 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 3 3 1 4 11 12 13 14 15 18 17 1s 19 2 4 S S 6 1 1 2 7 2 3 4 1 5 1 1 6 5 3 6 1 4 21 22 33 24 25 100 100 100 100 100 100 2 5 $ 6 S 2 3 6 1 . (2) Using the data in the table, construct ac chart based on the same of all the defects per sample Comment on the appearance of the chart (15 points] (b) Order the type of defects based on the frequency of occurrence and label the one occurring most frequently as very serious (or critical), the second most frequent as major and the least frequent occurring as a minor defect. [5 points) (e) Find the control limits of the chart for demerits based on your classification made in part b (Use ANSI/ASQC standards). Is the process under control? Why? [15 points]
