Thermistors are semiconductors used for measuring temperature. The electri- cal resistance of a thermistor changes with temperature. One model for the et- fect of temperature on a specific thermistor is R = 2,252e4000(-3.16), where R is the resistance in ohms and T is the temperature in K. You can verify that this thermistor has a resistance of 2,252 at 25°C = 298.16 K. For the data below, calculate the correlation coefficient for the model and decide whether the model fits the data well or not. Temperature (°C) Resistance (2) 7,850 10 4,400 2,900 20 1,500 1,000 30 40
