Final answer:
C. precise, but not accurate. Measurements that are consistent with each other but deviate from the accepted value are precise, but not accurate. They indicate repeatability but a systematic error may be present, and these measurements do not meet the standards to be considered accurate.
Step-by-step explanation:
When some measurements agree closely with each other but differ widely from the accepted value, these measurements are considered to be precise, but not accurate. Precision refers to the reproducibility of measurements, meaning if you perform the same measurement multiple times under the same conditions, you obtain very similar results each time. This is analogous to hitting the same spot on a target repeatedly, but not necessarily the bull's-eye. On the other hand, accuracy is about how close a measurement is to the true or accepted value. This would be like hitting the bull's-eye, even if the hits are not close to each other each time.
For example, imagine aiming darts at a dartboard: if all darts land close to each other but far from the bull's-eye, the throws are precise but not accurate. Another important point is that measurements that are precise but not accurate often indicate the presence of a systematic error. If the measuring equipment is flawed, such as a miscalibrated scale, it may provide consistent (precise) but incorrect (inaccurate) readings.
Lastly, it's important to clarify that such measurements would not be acceptable as a new standard of accuracy since they do not align with the true or accepted value. Accuracy is an objective criterion based on a known standard.
