Measurements of a patient's temperature are routinely done several times a day in hospitalsDigital thermometers are used, and it is important to evaluate thermometers and select the best one. The accuracy of these thermometers is checked by immersing them in liquids of known temperature. Such liquids include an ice-water mixture at 0.0and boiling water at 100.0C at exactly 1 atmosphere pressure (boiling point with atmospheric pressureSuppose the data shown in the following table were obtained on three available thermometers and you were asked to choose the "best one of the three Which would you choose? Explain your choice
