Use the least square regression to fit a straight line to the following data taken from the conductance (S/m) of a material with respect to the temperature (C) of a composite material used to absorb heat. Determine the conductance C(t) at the temperature of T = 22.5C using the derive linear regression function and the correlation coefficient r. (computed value round off to 5 decimal places)
