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 139 122 117 122 M2 122 126 135 123 M3 137 125 133 121 M4 118 130 125 125 M5 132 139 122 137 Does this process appear to be out of control? If yes, identify a machine using the factors of three sigma control limits. O a. M3 O b. M2 C. M5 Od. M4 O e. Process is in Control Of. M1
