1. A student is measuring the amount of water in a graduated cylinder and reports a value of 24 mL. The teacher reports a value of 24.2 mL. What is the student's percentage of error? What is the student's percentage of accuracy?

2. Another student was experimentally determining the boiling point of water. They reported it to be 99.5C. The accepted value for the boiling water is 100C. What is the percentage of error and the percentage of accuracy?

3. You ran an experiment three times. Below are the results. Find the percentage of precision. Trial Result 1 135 2 140 3 176

4. Suppose you did an experiment to determine the density of butter and you came up with a mean density of 900 kg/m. The known density of butter is 911 kg/m. Calculate the percentage of deviation and the percentage of precision.
