1. (20 pts, total) Name the most appropriate control chart for each of the situations described below: It is desired to quickly detect a large shift in the number of defective units inspected in lots of constant size 30. a. b. It is desired to rapidly find a large shift in the number of minor pixel defects present in a single model of computer display. 20 screens are inspected every 15 minutes. c. It is desired to quickly detect a large shift in the spread of a process that makes connecting pins. The operator measures the length of 5 sequential pins every 5 minutes. d. It is desired to detect a slow drift in the viscosity of a hydraulic fluid as each container is filled. e. It is desired to detect a large shift in the number of minor scratches on the surface of electrical panels. 25 panels of various size are inspected every half hour. f. It is desired to detect a large change in the variation of the axle size diameter by automatically measuring each one exiting the process and comparing it with the last one. g. It is desired to track the mean length of connecting pins by inspecting samples of size 6 every 10 minutes. Ideally, this will head off large shifts in the lengths. h. It is desired to catch a large shift in bearing size as each comes out of the press. The current diameter is averaged with the last five measurements before plotting on the chart. i. It is desired to track the fraction of defective fuses stored in six-packs by sampling 12 six-packs from shipping cartons of various sizes. j. It is desired to detect a large change in the spread of diameters from a bearing-making process by taking frequent samples of size 12 units every 20 minutes
