In separate experimental measurements by ten different students in a class for the value of the acceleration due to Earth's gravity in the same laboratory, the following results (in m/s2 ) were found: 9.82, 9.79, 9.68, 9.83, 9.81, 9.78, 9.72, 9.84, and 9.86. What is the precent error of the average value if the accepted value of g at that location is 9.81m/s2
