Random samples of size n = 330 are taken from a population with p = 0.09.
a. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the p⎯⎯p¯ chart. (Round the value for the centerline to 2 decimal places and the values for the UCL and LCL to 3 decimal places.)
Centerline _________
Upper control limit __________
Lower control limit __________
b. Calculate the centerline, the upper control
limit (UCL), and the lower control limit (LCL) for the p⎯⎯p¯ chart
if samples of 210 are used. (Round the value for the
centerline to 2 decimal places and the values for the UCL and LCL
to 3 decimal places.)
Centerline_____________
Upper control limit____________
Lower control limit____________
c. Discuss the effect of the sample size on the control limits. (fill in the blanks)
The control limits have a __________ spread with smaller sample sizes due to the _____________ standard error for the smaller sample size.
