Problem 2 A semiconductor company manufactures I CD panels for computer monitors Assume that a fraction nonconforming control chart was constructed with a constant sample size n = 100 . The control chart central line and control limits were found to be UCL = 0 09 Center Line = 0.06 LOL = 0.03 Assume that the process is in control . Use the following OC curve drawn for the above control limits to find Type II errors for the control chart if the actual non -conforming fraction is O . 1 . ( Answer : about .45 ) 2 ) Briefly explain the Type II error in terms of using the control chart Answer : It's the probability that the quality level has changed from 6 06 to a different value while the first sample after the change does not show such change )
