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	78	74	82	75
M2	82	82	83	85
M3	83	80	76	74
M4	76	83	86	79
M5	76	84	81	77

Does this process appear to be out of control? If yes, identify a machine using the factors of three sigma control limits.
