3. Determine the value of the f-statistic with a 0.95 cumulative probability. → 0.05
4. In Six Sigma methodology, a process operating at 6 sigma quality level produces approximately how many defects per million opportunities (DPMO)? → 3.4
5. Economic order quantity (EOQ) minimizes the sum of which two inventory costs? → Holding cost and ordering cost
6. What is the purpose of an acceptance sampling plan in quality control? → To determine whether to accept or reject a lot based on inspection of a sample
7. What is the purpose of sensitivity analysis in linear programming? → To determine how optimal solution changes with parameter variations
8. In a cost-benefit analysis for a public project, if B/C = 0.85, the project should be: → Rejected since benefits do not justify costs

12. A robot's configuration is → spherical
13. What does the term 'dead band' refer to in process control systems? → A range of input values that produce no change in controller output
14. A 95% confidence interval for a population mean is calculated as (47.2, 52.8). What is the sample mean? → 50.0
15. Which statistical tool is used to identify which defects account for the majority of quality problems, following the 80-20 rule? → Pareto chart
