The medicinal thermometer commonly required in homes can be read to +/-0.1 degrees F, whereas those in the doctor's office may be accurate to +/- 0.1 degrees C. Percent error is often expressed as the absolute value of the difference among the experimental value and the true value, divided by the true value: percent error= [abs (true value-experimental value)/true value] x 100%
State the percent error expected from each of these thermometers in calculating a person's body temperature of 38.9 degrees Celsius.
