(a) Use the thermocouple data in Table 11.3 and a computer to perform a linear least-squares fi t of voltage versus temperature for the range 0°C to 50°C and for the range 50°C to 100°C. Over which range is the fi t better? (b) Repeat your analysis of (a), this time using a second-order least-squares fi t (voltage will be a function of T and T ²). Compare your results with those you obtained in (a).
