    Question

    A researcher estimates a multiple regression model with two quantitative explanatory variables and their interaction. The estimated equation is: ŷ=24.1+0.08x11.09x21.77x1x2\hat{y} = 24.1+0.08x_{1}-1.09x_{2}-1.77x_{1}x_{2}. What does the equation look like if we have x2x_{2} keep constant at 1?


    1. FALSE: ŷ=24.10+0.08x1\hat{y} = 24.10+0.08x_{1}
    2. FALSE: ŷ=23.01+0.08x1\hat{y} = 23.01+0.08x_{1}
    3. TRUE: ŷ=23.011.69x1\hat{y} = 23.01-1.69x_{1}
    4. FALSE: ŷ=24.101.69x1\hat{y} = 24.10-1.69x_{1}
