Are there any points that are out of control? Set up and apply a tabular CUSUM for this process, using the same value of h and using a 50% head start. Are there any points that are out of control? Use a combined Shewhart-CUSUM scheme on the data, where the tabular CUSUM is used without any head start. Are there any points that are out of control? The Shewhart control chart to be used is the moving range chart.

Estimate the process standard deviation using the moving ranges.
It is decided to set up and apply a tabular CUSUM for this process in order to quickly detect if the mean
shifted to 960 (thus the magnitude of the shift to be detected is 10). Use the value h = 5. Are there any
points that are out of control?
Set up and apply a tabular CUSUM for this process, using the same value of h and using a 50% head start.
Are there any points that are out of control?
Use a combined Shewhart-CUSUM scheme on the data, where the tabular CUSUM is used without any
head start. Are there any points that are out of control? The Shewhart control chart to be used is the
moving range chart.
