Comparing to the use of a control chart using 3-sigma control limits, which of the following statement is correct? A. If we use 4-sigma control limits (instead of 3- sigma), Type I error will increase. (B. If we use 2-sigma control limits (instead of 3- sigma), then it is easier to incorrectly indicate an in-control process as an out-of- control process. C. If we use 4-sigma control limits (instead of 3- sigma), then it is easier to identify an out-of- control process. D. If we use 2-sigma control limits (instead of 3- sigma), then Type II error will increase. E. All of the above is correct
