Chapter 1, Problem 54QP

Three students $\left(\text{A, B, and C}\right)$ are asked to determine the volume of a sample of ethanol. Each student measures the volume three times with a graduated cylinder. The results in milliliters are: $\text{A }\left(\text{87}\text{.1, 88}\text{.2, 87}\text{.6}\right)\text{; B (86}\text{.9,87}\text{.1,87}\text{.2); C }\left(\text{87}\text{.6, 87}\text{.8, 87}\text{.9}\right)$. The true volume is 87.0 mL. Comment on the precision and the accuracy of each student s results.
