From the above output, the coefficient of constant is 0.667, the coefficient of X1 is 0.108, the
coefficient of X2 is 0.226, the coefficient of X3 is 0.400, the coefficient of X4 is -0.210, the coefficient
of X5 is 0.080 and the coefficient of X6 is -0.086.
Then, the regression equation is
Temperature change = 0.667 +0.108.X₁ +0.226X₂ +0.400X; -0.210X4+0.080X, -0.086X,
Solution
The regression equation is
Temperature change = 0.667 +0.108X₁ +0.226X₂ +0.400X3 -0.210X₁ +0.080X, -0.086X,
