<p>IME 415 SAMPLE QUIZ #6 Name 1 points per question (30 questions on actual quiz)</p><p>Starting time: Ending time: </p><p>This is a timed, 45-minute quiz over the basic concepts covered in IME 415. It is intended to determine how many of the basic concepts you understand. Please read each question and the answers carefully before you make your response. Some questions are as simple as they appear, and others require careful reading. If a curve is applied to the total score, questions that are bolded will be especially considered in computing the curve. Put your answer on the SCANTRON and turn in both the SCANTRON and the quiz together (not stapled).</p><p>1. Suppose typical , R-charts are kept for a parts machined on a lathe. How would the wearing out of the tool bit most likely show up on the x-chart? a) a run b) a point below the LCL c) a trend d) a cycle e) none of the above</p><p>2. Suppose a process is really in control and a sample point on the range chart is above the UCL. This causes a search to begin for an assignable cause. This situation is an example of: a) a Type II error b) a Type I error c) how SPC finds assignable causes d) a process that is not capable e) none of the above</p><p>3. Suppose an assembly line produces anywhere from 100 to 300 parts per day. The number of units that fail the functional test and must be scrapped is recorded at the end of the day. What kind of SPC chart would be most appropriate for tracking this data? a) p-chart b) np-chart c) , R-chart d) u-chart e) none of the above</p><p>4. Suppose a process has a Cp=1.0 and a measurability study shows that the P/T ratio is 0.55. Which of the following assessments is the most appropriate? a) Both the process and the measurement system are capable b) The variation among operators doing the measurement is excessive c) The measurement system is not adequate and the process capability is not certain d) The measurement gages need to be replaced e) all of the above</p><p>5.
