A process that is in control has a mean of μ = 12.5 and a standard deviation of σ = .8. a.  Construct an x 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. The input in the box below will not be graded, but may be reviewed and considered by your instructor.
