Lower Control Limit (LCL- ) = _____ units (round your response to two decimal places). B) Determine the 2-sigma x-chart control limits Upper Control Limit (UCL-) = units (round your response to two decimal places). units (round your response to two decimal places). Lower Control Limit (LCL-) = How do the control limits change? A-The control limits for the 2-sigma overbar x-chart and for the 3-sigma x -chart are the same B- The control limits are tighter for the 2-sigma overbar x -chart than for the 3-sigma x -chart. C- The control limits are tighter for the 3-sigma overbar x -chart than for the 2-sigma x -chart.

**Control Limits for X-Chart** ### a) Determine the 3-sigma x-chart control limits - **Upper Control Limit (UCL):** ____ units (round your response to two decimal places). - **Lower Control Limit (LCL):** ____ units (round your response to two decimal places). ### b) Determine the 2-sigma x-chart control limits - **Upper Control Limit (UCL):** ____ units (round your response to two decimal places). - **Lower Control Limit (LCL):** ____ units (round your response to two decimal places). ### How do the control limits change? - **A**: The control limits for the 2-sigma overbar x-chart and for the 3-sigma x-chart are the same. - **B**: The control limits are tighter for the 2-sigma overbar x-chart than for the 3-sigma x-chart. - **C**: The control limits are tighter for the 3-sigma overbar x-chart than for the 2-sigma x-chart. --- **Explanation:** This content is designed for educational purposes related to quality control in processes. The control limits help in determining whether a process is in statistical control. The 3-sigma and 2-sigma x-charts mentioned here are used to monitor the process mean over time with different confidence levels.

**Process Monitoring in Statistics** In this example, we consider a case where you are attempting to monitor a particular process. Important statistical parameters for this process are presented as follows: 1. **Overall Average (Mean):** The overall average of the process is measured to be 50.0 units. 2. **Population Standard Deviation:** The standard deviation of this process's population data is 1.84 units. 3. **Sample Size:** The sample size taken for this process monitoring is 16. Understanding these key parameters is crucial for any statistical analysis or quality control measures applied to the process. The overall average provides insight into the central tendency of the process measurements, whereas the population standard deviation indicates the variability around this average. The sample size determines the number of observations taken from the process. By considering the mean, standard deviation, and sample size, one can carry out further statistical analyses such as hypothesis testing, confidence interval estimation, and process capability analysis to ensure the process is operating within acceptable limits.
