    CP Index

    I'm looking through my textbook and I cannot find anything on the CP Index, meanwhile I have a CP Index question on my homework. Is the CP Index, C, which deals with how many defectives a lot will accept?

    Based on the first formula given on that website would you say that if someone was given a LSL of 24 and a USL of 44. And, the production process has a variance of 9. The Cp Index therefore would be 44-24 = 20; 20/9 ..and whatever that number comes out to would be the Cp Index?
