an Xbar and s chart was prepared for an operation using 25 samples with 6 pieces in each sample. Xbarbar was found to be 12.68 and sbar was 2.45. During production, a sample of 6 was taken and the pieces measured 11,13,14,14,10, and 12. At the time this sample was taken: A only the average was outside the control limits B neither the average nor standard deviation were within the control limits only the standard deviation was outside the control limits D both average and standard deviation were within the control limits
