The data in Table 9E.3 are temperature readings from a chemical process in C, taken every two minutes. (Read the observations down, from left.) The target value for the mean is 0 = 950.

(a) Estimate the process standard deviation.

(b) Set up and apply a tabular CUSUM for this process, using standardized values h= 5 and k = ½. Interpret this chart.
