Question:
The specifications for a product characteristic are: 0.3027 ± 0.008. The values given below are the last two figures of the dimension reading, that is, 23 means 0.3023. Sample Size n is 5.
Sample No. x R 1—————— 24—————7 2——————19—————5 3——————28—————3 4——————26—————2 5——————26—————9 6——————21—————2 7——————25—————4 8——————29—————6 9——————31—————2 10–––––––––30—————3 11–––––––––22—————6 12–––––––––24—————14 13–––––––––19—————3 14–––––––––27—————3 15–––––––––28—————5 16–––––––––29—————7 17–––––––––22—————5 18–––––––––28—————4 19–––––––––21—————5 20–––––––––18—————7
(a) Compute the trial control limits.
(b) Construct the stable control charts.
(c) Draw the specification limits on the chart and interpret your results. (Is the process able to satisfy the specifications?)
