Reconsider the viscosity data in Exercise 15-22. Construct a CUSUM control chart for this process using Î¼₀= 500 as the process target. Explain how you determined your estimate of Ïƒ and the CUSUM parameters H and K.

Exercise 15-22

The viscosity of a chemical intermediate is measured every hour. Twenty samples each of size n = 1 are in the following table.
