The data in Table 1 represent individual observations on molecular weight taken hourly from a chemical process. The target value of molecular weight is 1050 and the process standard deviation is thought to be abouts= 25. Set up a tabular cusum for the mean of this process. Design the cusum to quickly detect a shift of about 1.0 sin the process mean.
