    Question

    Given are the following three regression equations:

    ŷ=0.51+0.06x1\hat{y} = -0.51+0.06x_{1} ŷ=7.780.04x2\hat{y} = 7.78-0.04x_{2} ŷ=7.51+0.10x1+0.08x2\hat{y} = -7.51+0.10x_{1}+0.08x_{2}

    How much does the expected mean at y increase if x1x_{1} increases by 1 unit and x2x_{2} is kept constant?


    1. FALSE: 0.08
    2. FALSE: 0.06
    3. TRUE: 0.10
    4. FALSE: -0.04
