correct
Explanation
The correct answer is 4. Find an assignable cause.
In a control chart, the "rule of seven" indicates that if seven consecutive data points are on one side of the mean, it suggests that the process is likely not in statistical control, even if the points are within the control limits. This could be a sign of an underlying issue or trend that needs to be addressed. The appropriate action is to find an assignable cause for this deviation and take corrective measures if necessary. Simply modifying the mean or redoing measurements without investigating the cause would not address the potential issue.
