detailed graph to illustrate your answer. (25pts) 1)Explain how you would use the Taguchi loss function to improve the quality of a process. Use a 2) A manufacturer of Printed Circuit boards (PCB) periodically examines them for quality Subgroups of SO Printed Circuit boards (PCB) each are selected and examined for defects. The folle data shows the number of PCB with at least one defect when examining a subgroup each day 1)9; 2) 6,3 16,4) 6,5)3;6)5:7 14:8 17:9) 5; 10 )7:11) 11;12) 11; 13 17; 14) 12:15) 12:16)3;17) 15:10 19) 4; 20 )13:21)8:22) 5; 23)10; 24)13; 25) 2. a) What would be the appropriate control chart(s) that can be used for this analysis and why.
