A Chemistry 20 student uses a thermometer and a hot plate and measures the boiling point of ethyl alcohol to be 71.1 °C. Then, she looks in a reference book and finds that the actual boiling point of ethyl alcohol is 78.4 °C. What is her percent error? Do not show your work in the space provided. Record only your final answer with the correct number of significant digits and the proper units.
