Answer #1

Given,

USL=4.5 , LSL=3.5 , and  =0.09

capability index (Cp)= USL- LSL/6

Cp=4.5-3.5/6*0.09

Cp=1.8518

Cp>1

# The process is currently capable

    What does the phrase “in control” mean with respect to processes? An in-control process is one in which the output falls within the specification limits. An in-control process is statistically stable; it is free of assignable or non-random variation An in-control process is one in which the process width (i.e., 6σ) is substantially wider than the specification width (i.e., the upper specification limit minus the lower specification limit) None of these is correct
