    Question

    The regression equation representing the relationship between y (postmeasurement) on the one hand and sex (z = 1 for women; z = 0 for men) and x (premeasurement) on the other hand is ŷ=4+0.45x+0.9z\hat{y} = 4+0.45x+0.9z. The mean premeasurement is 9 for women and 7 for men. The overall premeasurement mean is 8.

    For women, determine the adjusted mean (“adjusted mean”) on the post-measurement.


    1. FALSE: 7.60
    2. FALSE: 8.05
    3. TRUE: 8.50
