Random samples of size n = 200 are taken from a population with p = 0.08.

a. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the p¯chart

b. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the p¯ chart if samples of 120 are used.

c. Discuss the effect of the sample size on the control limits. The control limits have a ___ spread with smaller sizes due to the_____ standard error for the smaller sample size.
