Correct answer: B
Explanation
The purpose of setting upper and lower control limits on a control chart is to provide a reference point for determining if the process is performing within acceptable parameters. If the data points fall outside of these limits, it indicates that corrective action needs to be taken in order to bring the process back into its desired state.Discussion
