Question: You are measuring a process whose mean has traditionally been 5?m and whose variance has traditionally been 2/3 ?m². You monitor the process with a control chart whose LCL and UCL are 4 and 6 ?m respectively using samples of size n = 6. The process mean shifts to 4.5?m, but the variance does not change. What is the probability of making a Type II error on the first sample after the shift? YOU MUST SHOW WORK to receive any credit.
