2 Below are 25 True-False Questions, worth 2 points each. Write one of "T" or "F" in front of each. _____ 1. The percent impurity in one fluid ounce of a liquid product is tested and plotted once per hour in a production facility. The appropriate control chart limits are p chart limits. _____ 2. A mean number of non-conformities per unit plotted on Shewhart control chart can exceed 1.0. _____ 3. The upper standards given control limit for ranges increases as the sample size increases. _____ 4. The upper standards given control limit for standard deviations increases as the sample size increases. _____ 5. Upper and lower standards given control limits for fractions non-conforming get further apart as the sample size increases. _____ 6. A point plotting outside of control limits on a Shewhart chart always suggests process degradation. _____ 7. A standard " " used in setting x chart control limits represents only "process" variation. _____ 8. Engineering specifications on dimension A are 1.00' .02' , while specifications on dimension B are 1.00' .01' . Then samples of size 5 n must produce x chart control limits that are tighter for dimension B than for dimension A. _____ 9. Engineering feedback control can play a part in establishing industrial process stability that is then monitored using statistical process control. _____ 10. " Special cause variation" is another name for "process change" that Shewhart control charting is meant to detect. _____ 11. Retrospective control limits are meant to help answer the question "Are process parameters at their standard values?" _____ 12. Statistical tolerance limits are intended to indicate the requirements on a measurement in order for a corresponding item to be functional. _____ 13. Statistical prediction limits are intended to locate most of the future output of a stable process based on a sample from that process. _____ 14. pk C is a measure of present process performance (rather than process potential). _____ 15. If a 95% confidence interval for pk C is   1.5,1.7 then it is reasonably clear that a "6 sigma" process performance goal has been achieved.

3 _____ 16. The ARL concept is a tool for aiding the choice/design of a process monitoring scheme, in that it is a quantification of monitoring scheme performance under a particular model of process behavior. _____ 17. The "Western Electric Alarm Rules" are meant to provide the ability to quickly detect non-random patterns on a Shewhart chart. _____ 18. Tool wear in a turning process that would naturally make consecutively machined cylinders increase in size can potentially be compensated for by the use of engineering feedback control. _____ 19. A physically stable process will of necessity produce acceptable product. _____ 20. Trends on an individuals chart tend to make the corresponding value of /1.128 MR "too small" as an estimate of " ".
