• Chose C3

  Rule of seven indicates if 7 data points are consecutively above or below the mean, it is out of control.

• 6

  C. On a control chart, when seven consecutive data points fall on the same side of the mean, either above or below, the process is said to be out of control and in need of adjustment. All the seven points may be within the control limits.

• Chose C5

  It's been about seven hours since anything's been outside of the limits, but the data points are mostly above the mean. Rule of sevens says seven points fall on one side of the mean, it's an assignable cause. So it's out of control.
