10. The probability of concluding that assignable variation exists when only random variation is present is: 1. the probability of a Type I error II. known as the alpha risk III highly unlikely IV. the sum of probabilities in the last two tails of the normal distribution. A) Increase the sample size to get a better measure. B) Nothing: the process is behaving as expected C) Explore the assignable causes because three observations are above the center line. D) Explore assignable causes because there is an increasing run or trend. A) I and II B) I and IV C) II and III D) I. II and IV E) I, III and IV 14. Which of the following statements is TRUE? A) The smaller the process capability ratio (C), the more capable the process is. B) Quality issues can be ethical issues. C) Scatter diagrams are useful for mangers to set priorities for improvement. D) Pareto charts can help reveal central tendency and dispersion 11. Which of the following statements is not true? A) If a process is in statistical control, there are no causes of variation B) If a process is not in statistical control. assignable causes of variation should be sought. C) If a process is in statistical control, there are only random causes of variation D) When assignable causes of variation exist, the process generates different distributions of the quality characteristic over time. 15. Which of the following is not a key philosophy of TOM? A) continuous improvement B) involvement of everyone C) quality rests on inspectors D) customer driven quality 16. Which area of an organization has responsibility for quality? A) quality assurance department B) packaging and shipping department C) top management D) customer service department E) All of the above 12. An operator of a filling machine plotted the weights of each bag he filled every day for a month. At the same time, a quality inspector randomly took groups of five bags of the same output and plotted the average weights of the samples. The inspector&#39;s sampling distribution A) will have greater variability than the operator&#39;s distribution B) will show if the output has been produced to the operators specifications C) will have less variability than the operator&#39;s distribution D) will have a mean five times greater than the operator&#39;s distribution 17. Quality planning and administration, quality training and quality control procedures are examples of A) internal failure costs. B) external failure costs. C) appraisal costs D) prevention costs 18. Which of the following is useful for improving quality? A) Six Sigma B) Total quality management C) Kaizen D) The seven tools E) all of the above 13. The center line on a p-chart is 0.50 with an UCL of 0.65 and a LCL of 0.35. The results of the next six samples are 0.40.0.37.0.45. 0.48, 0.57, and 0.64. What should you do?
