What is the average run length (ARL) until an x control chart signals a false alarm if the control limits are set at ±2.5 standard errors from the centerline?
The probability of a Type I error for each sample is .0124 [namely, P(| z | > 2.5], hence the ARL = 1/.0124 = 80.6 ? 81 samples should be taken.
