Consider the papermaking process in Exercise 6.15. Set up a u chart based on an average sample size to control this process.
Answer to relevant QuestionsThe number of nonconformities found on final inspection of a tape deck is shown in Table 6E.11. Can you conclude that the process is in statistical control? What center line and control limits would you recommend for ...An automobile manufacturer wishes to control the number of nonconformities in a subassembly area producing manual transmissions. The inspection unit is defined as four transmissions, and data from 16 samples (each of size 4) ...Suggest at least two nonmanufacturing scenarios in which attributes control charts could be useful for process monitoring. Based on the data in Table 6E.6 if an np chart is to be established, what would you recommend as the center line and control limits? Assume that . a. Derive an item-by-item sequential-sampling plan for which p1 = 0.02, α = 0.05, p2 = 0.15 and β = 0.10. b. Draw the OC curve for this plan.
