Question: a . Calculate the centerline, the upper control limit ( UCL ) , and the lower control limit ( LCL ) for the x chart

a. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the x
chart if samples of size 6 are used. (Round the value for the centerline to the nearest whole number and the values for the UCL and LCL to 2 decimal places.)
b. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the x
chart if samples of size 12 are used. (Round the value for the centerline to the nearest whole number and the values for the UCL and LCL to 2 decimal places.)
c. Discuss the effect of the sample size on the control limits.a. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the x
