A process that is in control has a mean of =12 and a standard deviation of =0.8. a. Construct an x control chart if samples of size 5 are to be used (to 1 decimal). For n=5 Find the UCL = Find the LCL= b. Repeat part (a) for samples of size 7 and 14 (to 2 decimals). For n=7 Find the UCL = Find the LCL = For n=14 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. UCL and LCL become closer together as n If the process is in control, the larger samples should have less variance and should fall to 12
