The table below lists the height h (in cm), the age a (in years), the gender g (0="Female", 1-"Male"), and the weight w (in kg) of some college students. We wish to fit a linear function of the form Height Age Gender Weight 20 19. 21 23 22 w=w(h,a,g) = 163 170 168 157 184 0 1 0 0 1 61 73 66 54 88 w co+ch + c₂a + cag which predicts the weight from the rest of the data. Find the best approximation of this function, using least squares.
