question 48

Multiple Choice

Suppose that you have calculated the control limits for a p-chart to be the following:
LCL = 0.02 and UCL = 0.08.
Today, you took 10 samples of 20 units each. The first nine samples each had one defect. The last sample had zero defects. What can you conclude?

• A) the process is out of control
• B) the process is in a state of control
• C) the last sample should be ignored because it was "too good"
• D) you calculated the limits incorrectly because the LCL must be either negative or 0
• E) the sample size must be increased
