To determine whether the measured values are accurate and/or precise, we need to understand the definitions of accuracy and precision:<br /><br />- Accuracy refers to how close a measurement is to the true or accepted value.<br />- Precision refers to how close repeated measurements are to each other.<br /><br />Given the accepted value of 1001 mA and the measured values of 1005 mA, 996 mA, and 1001 mA:<br /><br />1. **Accuracy**: <br /> - The accepted value is 1001 mA.<br /> - The measured values are 1005 mA, 996 mA, and 1001 mA.<br /> - The value 1001 mA is exactly the accepted value, making it accurate.<br /> - The value 996 mA is close to the accepted value, making it also somewhat accurate.<br /> - The value 1005 mA is not close to the accepted value, making it inaccurate.<br /><br />2. **Precision**:<br /> - The measured values are 1005 mA, 996 mA, and 1001 mA.<br /> - The values 996 mA and 1001 mA are close to each other, indicating they are precise.<br /> - The value 1005 mA is not close to the other values, indicating it is not precise.<br /><br />Based on this analysis:<br />- The value 1001 mA is both accurate and precise.<br />- The value 996 mA is accurate but not precise.<br />- The value 1005 mA is neither accurate nor precise.<br /><br />Therefore, the correct answer is:<br />**Both Accurate and Precise** (specifically for the value 1001 mA).
