Consider a normally distributed population with mean \mu : 80 and standard deviation \sigma =14. a. Calculate the centerline, the upper control limit and the lower control limit for the X chart if samples of size 4 are used. Centerline Upper Control Limit Lower Control Limit b. Calculate the centerline, the upper control limit, and the lower control limit for the X chart if samples of size 8 are used. Centerline Upper Control Limi Lower Control Limit c. Discuss the effect of the sample size on the control limits. The larger sample size gives standard error. I control limits due to the
