A process that is in control has a mean of # = 18.5 and a standard deviation of o = 0.8. (a) Compute the upper and lower control limits if samples of size 4 are to be used. UCL = LCL = Construct the x chart for this process. 21.0+ 21.0+ 21.0+ 20.5+ 20.5 + 20.5+ UCL 20.0+ UCL 20.0+ 20.0 19.5 19.5 + UCL 19.5 - 19.0- 19.0 19.0+ Sample Mean x 18.5 18.5 Sample Mean x 18.5 18.0 18.0 18.0- 17.5 Sample 17.5 LCL 17.5 17.0 LCL 17.0+ 17.0 16.5 16.5+ 16.5+ LCL 2 4 6 8 10 2 4 6 8 10 2 4 6 8 10 O Sample Number Sample Number Sample Number 21.0 + 20.5 + 20.0+ UCL 19.5- 19.0+ Sample Mean x 18.5 18.0 17.5 17.0 LCL 16.5 2 4 6 8 10 C Sample Number(b) Compute the upper and lower control limits if samples of size 8 are to be used.

Discuss why this is reasonable. The limits become ---Select--- as n increases. If the process is in control, the larger samples should have ( ---Select--- C variance and should fall ( ---Select--- C # = 18.5
