As a production manager for an electric circuit company you have encountered the following situation:
A process for producing electronic circuits has achieved very high yield levels. An average of only 10 defective parts per million is currently produced.
1. What are the upper and lower control limits for a sample size of 100?
2. Recompute the upper and lower control limits for a sample size of 10,000?
3. Which of these two sample sizes would you recommend? Explain.
