Question 2: a) A garments manufacturing unit observes the defects of one day from the inspection of 25000 garments. The severity of each defect is classified in the following: i. Critical ii. Major iii. Minor iv. Trivial The complete checklist comprises of 50 types of defects. The data of 1st January 2021 of 25000 garments reveals the following figures: Total no. of Critical Defects: 2 Total no. of Major Defects: 40 Total no. of Minor Defects: 250 Total no. of Trivial Defects: 300 Calculate the DPU (Defects / Unit), DPO (Defects / Opportunity), Yield, Sigma Value and the DPMO (Defects / M. Opportunities) for the year 1st January 2021. b) you receive a shipment of 25,000 garments. You either cannot or do not want to inspect the entire shipment. Develop a plan with acceptance sampling to determine how many garments you need to examine (sample size) and how many defects are allowed within the sample (acceptance number). In this case, suppose your acceptable quality level (AQL) is 4.0% and the reject-able quality level (RQL) 0r LTPD is 5.0%, and you assume alpha = 0.05 and beta = 0.10.
