An x-bar chart is used to monitor the central tendency of a process over time. If the data points fall within the control limits and show no particular pattern or trend, the process is considered to be in control. In this case, the data points in Table 5.4 fall within the control limits and show no significant trends or patterns, indicating that the process is in control. Therefore, the conclusion would be that the process is in control.
