2 Below are 25 True-False Questions, worth 2 points each. Write one of "T" or "F" in front of each. _____ 1. Modern quality assurance is fundamentally process-oriented. _____ 2. If a production process is made to be consistent/physically stable, then it will of necessity produce good/functional product. _____ 3. Most effective process improvement analysis is based on data mined from large general- purpose databases. _____ 4. Shapes of histograms can provide clues to physical origins and thus clues about the operation of processes that generated the data being summarized. _____ 5. Complicated multi-step production processes are most effectively monitored through "end-of-the-line" inspection where a whole final product can be inspected, and causes of problems can thus be easily diagnosed. _____ 6. A bell-shaped histogram of consecutively-produced widget diameters is evidence that a production process is operating consistently over time, so nothing more can be revealed by plotting a run chart. _____ 7. A Pareto diagram is used to focus attention on the biggest causes of process problems. _____ 8. Without effective measurement systems, it is impossible to know whether a business or production process is performing well. _____ 9. Without appropriate routine collection and analysis of process data, it is impossible to know whether a business or production process is performing well. _____ 10. Measurement variation will typically inflate one's perception of process variation (based on the measurement of a sample of parts produced by a process). _____ 11. When measurement is destructive, there is no possibility of evaluating the size of pure repeatability variation. _____ 12. The width of a confidence interval for a standard deviation, , tells one about the size of . _____ 13. In order to compare biases of two measurement devices, one needs at least two "standards" (items with known values of measurands). _____ 14. Measurement device A is known to be linear, but is not known to be properly calibrated. I wish to know if device B is linear. That can be determined using A and B only if standards are available. _____ 15. A gauge R&R study typically reveals which of several operators produces the most accurate measurements.

3 _____ 16. If widget diameters have actual standard deviation .01 mm and measurement has standard deviation .01 mm , then measured diameters can be expected to exhibit a standard deviation of .02 mm . _____ 17. In an R&R context, limitations on the amount of information available on reproducibility related to a relatively small number of operators being included in the study can be overcome by use of a large number of parts. _____ 18. If a gauge capability ratio (or precision to tolerance ratio) is at least 1.00, the gauge in question is probably adequate for checking conformance to the engineering specifications under study.
