Explanation / Answer

We have different models, If which model has Adjusted R^2 is very high compare the other models then the model is best predicted equation.

In our example, 1st model has adjusted R^2 is high (0.818) with three indepedent variables compare to all other models.
So first model is best regression equation.

The best predicted value of this males weight is
Y-hat = -199 + 2.4(75) + 2.1 (100) - 0.1(226) = 168.4
