RE = ((actual-expected)/expected)x100% (Wed) Using a thermometer, the room’s actual temperature is 75 °F. The expected temperature from the thermostat is 72 °F. What is the relative error of the room’s temperature in percent? (5 min/5 pts) Actual = 75 °F (measured) Expected = 72 °F (from hypothesis) RE = ((75 °F – 72 °F)/(72 °F))x100% RE = % RE = 4.2%
