Why does Six-sigma correspond to a process capability of 2.0? Explain with specific reference to OM7011 lecture content.
ii. Suppose that a specification calls for LSL = 3.0 and USL = 7.0. A sample of 100 parts found an average process output value of X̄ = 5.75 with sample standard deviation σ = 0.5. Calculate the process
capability index value Cp. Is the process capability value satisfactory (in terms of defect probability)?
Should the manager consider any action, if so, what and if not, why not?
