Consider the control chart below. R-chart I 2 3 45 6 789101112131415 Sample Q Is this process in statistical control? O No. There is at least one point beyond the control limits. 0 Yes. There is no point beyond the control limits. (O) No. There is no point beyond the control limits. 0 Yes. There is at least one point beyond the control limits. A sample of 5 boxes was selected from a process each day for 8 days. The weight of each box (in ounces), along with the sample range and mean are shown below: Process Data Day Box 1 Box2 Box3 Box4 Box5 Range Mean 1 50 54 54 50 54 4 52.4 2 49 54 47 47 54 7 50.2 3 53 50 52 52 50 3 51.4 4 52 49 47 47 49 5 48.8 5 50 49 46 52 51 6 49.6 6 51 49 48 51 52 4 50.2 7 48 52 47 54 53 7 50.8 8 50 50 52 46 48 6 49.2 Determine the control limits for the a-chart accurate to 2 decimal places. Table of Control Chart Constants a ) Centreline = b) LCL = UCL = c) Can we conclude that the process mean is out of control? O No. There is no point beyond the control limits. O Yes. There is at least one point beyond the control limits. O No. There is at least one point beyond the control limits. O Yes. There is no point beyond the control limits.The sample mean and ranges for 20 samples, each of size n = 9, from a manufacturing process are provided below.
