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 #2 #3 Select one: a. 9.88 and 0 Ob. 4.94 and 0 c. 11.14 and 0 O d. 8.66 and 0 17 16 23 e. 23.16 and 16.84 Measurements 15 25 24 15 Using the factors for three sigma control limits, what are the sample range (R) chart upper and lower control limits? 18 23 17 25 22
