A process that is in control has a mean ofμ = 12.5 and a standard deviation ofσ = .8.

a.Construct anx chart if samples of size 4 are to be used (to 1 decimal).

For n=4:
Find the UCL =
Find the LCL =

b.Repeat part (a) for samples of size 8 and 16 (to 2 decimals).

For n=8:
Find the UCL =
Find the LCL =

For n=16:
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 change is reasonable.
