17. (10points) One hundred product labels are inspected every day for surface nonconformities. Results for the past 25 days are 22, 29, 25, 17, 20, 16, 34, 11, 31, 29, 15, 10, 33, 23, 27, 15, 17, 17, 19, 22, 23, 27, 29, 33, and 21. Plot the points on graph paper (run chart) and determine if the process is stable. Determine the trial central line and control limits. (Hint: count of defects/unit)

The data represents the copper concentration in a plating process. Copper concentration in a plating pool is controlled by an automated colorimeter that takes readings and adjusts the concentration as required. To verify the correct functioning of a new colorimeter system copper concentration is measured manually six times per shift. (a) Plot an x-bar and R control chart for this process. Perform runs tests to Westem Electric rules 1 through 5 in Table 5.1, p. 205 of the textbook. Is...
