# Question

A control chart for nonconformities is to be constructed with c 2.0, LCL = 0, and UCL such that the probability of appoint plotting outside control limits when c = 2.0 is only 0.005.

(a) Find the UCL.

(b) What is the type I error probability of the process is assumed to be out of control only when two consecutive points fall outside the control limits?
