*(Round your answers to 4 decimal places, e.g. 1.7578.)
**(Round your answers to 3 decimal places, e.g. 1.757.)
The regression equation for given model is: ŷ = enter an appropriate value rounded to 4 decimal places * + enter an appropriate value rounded to 4 decimal places * x1 + enter an appropriate value rounded to 4 decimal places * x2
R2 = enter an appropriate value rounded to 3 decimal places ** and expected value of R2 = enter an appropriate value rounded to 3 decimal places **.
Thus, we select an option can expect/can't expect to find R2 close to the true value of enter an appropriate value rounded to 3 decimal places ** purely by chance.
