Question

a student is checking the density of a gold nugget. the known density of gold is 19.32 g/cm³. the student tests the nugget three times and comes up with 19.18 g/cm³, 19.17 g/cm³, and 19.19 g/cm³. how reliable is this data? the data has low precision but higher accuracy. the data has low precision and low accuracy. the data has high precision but lower accuracy. the data has high precision and high accuracy.

Explanation:

Precision refers to how close the measured values are to each other. The measured values 19.18 g/cm³, 19.17 g/cm³, and 19.19 g/cm³ are very close, indicating high precision. Accuracy is how close the measured values are to the true - value. The true density of gold is 19.32 g/cm³, and the measured values are lower than this, showing lower accuracy.

Answer:

The data has high precision but lower accuracy.
