In the field of electrical engineering, Control Charts are widely used for process monitoring and quality control.

The dataset provided includes a control chart representing the Sample Numbers and the corresponding Sample Quality Characteristics:

The warning limits are shown as red lines.

Using the Wester Electrical Rule determine whether the process is in an in$-$control state or an out$-$of$-$control state.

Note: You need to describe all rule violations and identify the data points for each violation.
