A process for producing electronic circuits has achieved very high yield levels. An average of only 8 defective parts per million is currently produced.

a. What are the upper and lower control limits for a sample size of 100?

b. Recompute the upper and lower control limits for a sample size of 10,000.

c. Which of these two sample sizes would you recommend? Explain.
