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 164 166 178 160 M2 189 169 189 175 M3 160 176 171 163 M4 171 163 168 1165 M5 160 167 177 185 Does this process appear to be out of control? If yes, identify a machine using the factors of three sigma control limits. a. M1 b. M2 O c. M5 d. M4 O e. Process is in Control O f. M3
