A mixture of sucrose and water was heated on a hot plate

A mixture of sucrose and water was heated on a hot plate, and the temperature (in °C) was recorded each minute for 20 minutes by three thermocouples. The results are shown in the following table.

a. Compute the least-squares line for estimating the temperature as a function of time, using T1 as the value for temperature.

b. Compute the least-squares line for estimating the temperature as a function of time, using T2 as the value for temperature.

c. Compute the least-squares line for estimating the temperature as a function of time, using T3 as the value for temperature.

d. It is desired to compute a single line to estimate temperature as a function of time. One person suggests averaging the three slope estimates to obtain a single slope estimate, and averaging the three intercept estimates to obtain a single intercept estimate. Find the equation of the line that results from this method.

e. Someone else suggests averaging the three temperature measurements at each time to obtain T =

(T1 + T2 + T3)/3. Compute the least-squares line using T as the value for temperature. f. Are the results of parts (d) and (e) different?
