Raising the LCL and lowering the UCL, in the absence of any other changes, will have no effect on the process mean.
True
False
51.
The UCL and LCL can be set at any distance from the target or centerline, however, when they are set too far away, and if the process output level does shift, this shift may not be detected for quite some time. The reason for this is that even when the process does shift, the sample means from the shifted process may still fall within these wide UCL and LCL limits.
True
False

When setting the LCL and UCL positions on a control chart it will be necessary to balance the costs associated with ___________ errors.
Alpha
Beta
