A Quality Analyst wants to construct a control

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 1 Measurement 2 Measurement 3 Measurement 4 M1 291 276 320 272 M2 269 317 290 309 M3 278 274 291 304 M4 312 313 283 296 295 M5 315 276 320 Does this process appear to be out of control? If yes, identify a machine using the factors of three sigma control limits. . M2 O b. Process is in Control Oc M1 Od. M3 O e. M4 Of. M5
