Does a certain tympanic thermometer measure the same in both ears? We are investigating4 the reliability of a certain brand of tympanic thermometer (temperature measured by a sensor inserted into the patient’s ear). Sixteen readings ( F), eight per ear, were taken on a healthy patient at intervals of 1 minute, alternating ears. (We note that these are paired data, but they are also paired—matched—through time, because they all arise from the same patient.) Data were as in Table 11.31. Are the distributions of temperature readings for the two ears different?
