Answer:
Precise, but not accurate
Step-by-step explanation:
First, let's define precision and accuracy.
Precision: how close multiple measurements are
Accuracy: how close the measurements are to the true measurement
The three measurements are:
167.0 g, 166.9 g, 167.2 g
The true mass is 172 grams.
We can see that each measurement is far from the actual value of 172 grams: about 5 grams off. They are not close to the actual measurement, so they are not accurate.
The three measurements are very close to each other. They are all within 0.3 grams of each other. The measurements are all close to each other, therefore they are precise.
Therefore, the measurements are precise, but not accurate.
