1. The problem asks to state and briefly explain the key indicators of a properly centered process. 2. A properly centered process in quality control means the process average or mean is aligned with the target value or specification center. 3. Key indicators include: - The process mean ($\mu$) is equal or very close to the target value ($T$). - Control charts show data points fluctuating randomly around the center line without systematic shifts. - The process capability indices such as $C_p$ and $C_{pk}$ indicate the process is capable and centered; specifically, $C_{pk}$ is close to $C_p$, showing minimal shift from the target. 4. In simple terms, a properly centered process produces outputs consistently near the desired target, minimizing defects and variation. 5. This ensures the process is stable and meets quality requirements effectively.
