Question

A process that is in control has a mean of 12.5 and a standard deviation of 1.1.

a. Construct the  control chart for this process if samples of size  are to be used (to 1 decimal).

For N=4

Find the  UCL

Find the  LCL

b. Repeat part (a) for samples of size  and  (to 2 decimals).

For N=10

Find the  UCL

Find the  LCL

For N=15

Find the  UCL

Find the  LCL

c. What happens to the limits of the control chart as the sample size is increased? Discuss why this is reasonable.

 and  become - Select your answer (closerfarther) together as n increases. If the process is in control, the larger samples should have less variance and should fall - Select your answer (closerfarther) to 12.5
