It is not because there is a point outside the region between the upper and lower control limits.

Answer:

The correct answer is: It is not because there is an obvious pattern to the ranges.

Step-by-step explanation:

When looking at an R chart, one of the out-of-control criteria is the presence of an obvious pattern in the ranges. This can indicate that changes are happening in the process that are causing variation. If there is a consistent increase or decrease in the range values, or if the range values are alternating in a pattern, then the process variation is not within statistical control. In this case, it is important to investigate and address the source of the variation to improve the process and bring it back into control.
