The data in Table below represent individual observations on molecular Weight taken hourly from a chemical process. The target value for the molecular weight is 1,351} and the process standard deviation is thought to be about ct = 25 Table 3.

Design the CUSUM to quickly detect a shift of about LG {I in the process mean. {b} Analyze the data using a moving average control chart with w = 6. Compare the results obtained with the cumulative sum control chart
