Question

Question 16 (1 point) An X bar and R chart was prepared for an operation using 25 samples with seven pieces in each sample. X double bar was found to be 24.8 and R bar was 5.50. During production, a sample of seven was taken and the pieces measured 25, 32, 35, 28, 27, 24, and 26. At the time this sample was taken: Only the range was outside the control limits. Only the average was outside the control limits. Both the average and range were within the control limits. Neither the average nor range were within the control limits.
