#2: Attributes Control Charts INSTRUCTIONS: Use MINITAB 17 to complete the following exercises. You will need to read the data set description using the HELP command in order to make meaningful interpretations and in some cases in order to determine the appropriate attributes control chart to use. Remove out of control points only when instructed to do so; otherwise just interpret. Please submit your completed assignment, with relevant MINITAB output and comments, as ONE WORD document by the due date. This assignment is worth a total of 50 points. [10 pts] 1. Use the data file BCAPA.MTW. Construct a c chart for the number of weak spots found in a piece of wire. Assume that the length of wires examined was constant (ignore the lengths provided in C5). Use all tests to determine whether the process is in statistical control. If out of control points are identified, remove them and revise the c chart. Comment on the results. [10 pts] 2. Use the data file DOCS.MTW and construct an appropriate control chart (Hint: read the data set description carefully!). Use all tests to determine whether the process is in statistical control. Comment on the results. [10 pts] 3. Use the data file PAPER.MTW in the STUDENT8\\DATA folder to construct an appropriate control chart. (Hint: sum the number of defects across the 6 samples.) Use all tests to determine whether the process is in statistical control. Comment on the results. [10 pts] 4. Use the data file TOYS.MTW. Construct a p chart for the proportion of defective tires per lot. Use all tests to determine whether the process is in control. Comment on the results. statistical [10 pts] on the 5. Use the data file PLATING.MTW and construct an np chart. Use all tests to determine whether the process is in statistical control. If out of control points are identified, remove them and revise the np chart. Comment results
