Use least square regression to fit a straight line to the following data taken from the conductance (S/m) of a material with respect to temperature (C) of a composite material used to absorb heat. Determine the conductance C(t) at the temperature of T = 21.5C using the derived linear regression function and the correlation coefficient r.
