A Quality Analyst wants to construct a control

A Quality Analyst wants to construct a control chart for determining whether three machines, all producing the same product, are under control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results : Machine #1 measurements [20, 17, 19, 13]; Machine #2 measurements [ 12, 15, 17, 19]; Machine #3 measurements [ 16, 13, 12, 13]. Using the factors for three sigma control limits, what are x-bar chart upper and lower control limits? a. 21.62and 9.38 b. 33.5and -2.5 C. 19.88and 11.12 d. 17.12 and 13.88
