A Quality Analyst wants to construct a control chart for determining whether five machines, all producing the same product, are under control with regard to a particular quality variable. Accordingly, four units of putputs from each machine are collected: Machine Measurement Measurement Measurement Measurement 1 2 3 4 M1 216 215 223 235 M2 213 215 238 220 M3 216 224 231 203 M4 206 208 203 212 M5 218 225 213 203 Does this process appear to be out of control? If yes, identify a machine using the factors of three sigma control limits. O a. M5 O b. Process is in Control O c. M1 O d. M3 Oe. M4 Of. M2
