Need Help In Cynthia's physics class, she must turn in four lab reports. For each report, she earns extra credit if her percent error is less than 5%.
For her first lab report, she calculated the value of the acceleration due to gravity three times. She got the following three values.

9.56/ms^2 9.72/ms^2 9.88/ms^2

The accepted value of the acceleration due to gravity is 9.8/ms^2.
