{30 Samples Production Narrative} Looking at the chart developed in a previous question,you see indications of a possible level shift as well as cyclic variation.Explain how the chart shows this,and give a possible explanation.
Level Shift
A sudden change in the baseline level of a time series dataset.
Cyclic Variation
Represents recurrent fluctuations in a time series data over a period longer than one year, often tied to economic, environmental, or social cycles.
Indications
Signs or symptoms that suggest the presence of a particular condition or the need for a specific treatment or intervention.
- Identify indicators of problems in process control by analyzing control charts.
- Apply statistical process control methods to detect shifts or trends in manufacturing processes.

Final Answer :
Most of the points lie above the centerline and in fact tend to hover around one standard error above the centerline.You can also see a pattern of several points above this line followed by several points below this line.The level shift might be caused by a new machine or operator,and the cyclic variation might be caused by operator fatigue.
