Answer
The measurements cannot be used to show precision because they were each measured only once, not repeatedly which is required for establishing precision.
Explanation
1. Precision refers to the consistency or repeatability of measurements, i.e., if the measurements are close to each other, then they are precise. 2. To determine the precision of any method or tool, multiple measurements using the same sample or object are usually needed. This is because precision is about consistency or repeatability of results and it is usually being established through multiple measurements by reducing the chances of random anomalies. 3. As per the situation, the student only measured the volume of each fruit once. Single measurement for each fruit does not provide data on the repeatability or consistency of the student's volume measurements.4. Therefore, since there are no repeated observations for any fruit, we cannot use these results to accurately measure precision.
