Answer:
Precision
Explanation:
It figures out how close all of the data numbers are.
4) is correct
This is because water is polar and it will mix with a polar solvent. A good rule for remembering the behavior of non-polar and polar compounds when it comes to being miscible is that "like dissolves like."
