Given a situation where a control chart with 3-sigma

1. Question 2 Given a situation where a control chart with 3-sigma limits is being constructed to monitor the percentage of defective items produced by a process, if samples of 100 units each are taken from the process and the average percent defective found in the first 10 samples is .08 (8%), what is the upper control limit (rounded to two decimal places) for the process?
2. a..04
3. b..08
4. c..16
5. d..20
6. e..24

2 points

2. a. Two or more consecutive plots are close to the upper limit of the control chart.
3. b. A run of five or more consecutive plots are above the center line of the control chart.
4. c. A series of consecutive plots are evenly distributed close to the center line of the control chart.
5. d. A series of five or more consecutive plots exhibits an increasing trend towards the upper limit of the control chart.
6. e. A single plot falls below the lower limit of the control chart.
