1. What is the primary purpose of a control chart in quality management?
a. A control chart is used to calculate process costs.
b. A control chart is used to design new products.
c. A control chart is used to train employees.
d. A control chart is used to monitor process variation over time.
2. What is typically plotted on the center line of an X-bar chart?
a. The range of the process is plotted on the center line of an X-bar chart.
b. The standard deviation is plotted on the center line of an X-bar chart.
c. The number of defects is plotted on the center line of an X-bar chart.
d. The mean of the process is plotted on the center line of an X-bar chart.
3. Which condition indicates that a process is in control on a control chart?
a. A process is in control when all points are above the upper control limit.
b. A process is in control when all points are below the lower control limit.
c. A process is in control when points form a non-random pattern.
d. A process is considered in control when all points are within control limits
and display random variation.
4. What is the main use of a p-chart in statistical process control?
a. A p-chart is used to monitor the mean of a process.
b. A p-chart is used to monitor the range of a process.
c. A p-chart is used to monitor the proportion of defective items in a process.
d. A p-chart is used to monitor the time between failures.
