A graph for the non-conforming fraction used in a process with a sample size of 120 has the following parameters:

(Image attached)

a) Find the amplitude of the control limits in number of standard deviations.

b) Find the limits for an equivalent control chart, for the number of non-conforming units.

c) Determine the probability of not detecting a change in the mean of the process at 0.15

LCS = 0.090
LCC = 0.050
LCI = 0.01
Transcribed Image Text:LCS = 0.090 LCC = 0.050 LCI = 0.01
