A quality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are in control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine with the following results: Machine Measurements #1 17 15 15 17 22 16 25 18 25 #3 23 24 23 22 For upper and lower control limits of 23:29 and 16.71, which machines, if any, appearts) to have an out of control process meant please refer to the attached table for important parameter values) Ouality Table del machine #1 machine #2 machine #3 all of the machines none of the machines FACTORS FOR RCRARIS a control arts Number of Observations in Subgroup Factor for * Chart A LOWE Control Limit D Lipper Controllimit OOOOO 1.88 1.02 0.73 0:58 0.48 0.42 0.32 034 0.31 0.29 0.27 0.25 0.20 0.22 0.21 0:20 D. 0.19 OTO 0.08 0.14 0.18 0.22 0.26 0.28 TO 12 12 13 10 15 16 17 28 19 201 3.27 2.57 2.28 2.11 200 1.92 1.08 1.82 1.78 1.74 1.22 139 1.57 1.65 1.00 1.62 1.6T 1.80 10 0.37 01.25 DU 0.38 0.30 0440 0.41 CESTI
