1. What is the primary purpose of quality control (QC) in manufacturing?
   1. To increase production speed
   2. To enhance product design
   3. To reduce marketing costs
   4. To ensure products meet specific quality standards
2. Which of the following statistical methods is commonly used in quality control to monitor a process over time?
   1. Descriptive statistics
   2. Control charts
   3. Regression analysis
   4. Probability simulations
3. In a control chart, what do the upper control limit (UCL) and lower control limit (LCL) represent?
   1. The average process output over time
   2. The maximum and minimum values recorded
   3. The standard deviation of the process
   4. The expected variation within the process
4. What does the Process Capability Index (Cpk) measure in quality control?
   1. How well a process can produce products within specification limits
   2. The total number of defective products
   3. The average time taken to produce a product
   4. The proportion of products returned by customers
5. Which of the following is an example of a quality control tool used in statistical process control (SPC)?
   1. Pie chart
   2. Control chart
   3. Histogram
   4. Box plot

   1. To improve patient care by monitoring and analyzing treatment outcomes
   2. To speed up the patient admission process
   3. To reduce the number of healthcare professionals needed
   4. To increase the cost of medical services
7. What is the primary benefit of conducting a process capability analysis?
   1. It increases the overall production capacity
   2. It helps identify if a process can consistently produce within specified limits
   3. It reduces the time taken to complete a quality check
   4. It provides a summary of customer feedback
8. Which of the following types of control charts would you use to monitor the proportion of defective items in a process?
   1. X-bar Chart
   2. R Chart
   3. p Chart

   1. Regression analysis
   2. Process capability analysis
   3. Descriptive statistics
   4. Probability simulations
10. Why are control charts useful in quality control?
    1. They help determine the average cost of production
    2. They identify variations in a process and signal when corrective actions are needed
    3. They increase the speed of production
    4. They eliminate the need for quality inspections
