Resistors for electronic circults are manufactured on a high-speed automated machine. The machine is set up to produce a large run of resistors of 1,000 ohms each. Use Exhibit 10.13. To set up the machine and to create a control chart to be used throughout the run, 15 samples were taken with four resistors in each sample. The complete list of samples and their measured values are as follows: Use three-sigma control limits.

Case Part B: Patient Satisfaction Thirty patients who check out of the Metropolitan General Hospital each week are asked to complete a questionnaire about hospital service. Since patients do not feel well when they are in the hospital, they typically are very critical of the service. Management recorded the number of patients who indicated dissatisfaction of any kind with the service for each 30-patient sample for a 16-week period (see Excel file, Hospital Case Part B spreadsheet). Perform a data analysis for the Hospital. Prepare a report that summarizes your findings and recommendations. Include the following: Questions for Part B: 1. What type of control chart would you use to monitor customer satisfaction at the hospital? 2. Construct the appropriate three-sigma control chart. 3. What comments can you make about the results of the questionnaire? Does the current process appear to be in control? Explain.
