Question

For the regression equation, Ŷ = –2X + 6, if the X value is above the mean (positive deviation), what can be determined about the predicted Y value?

Answer 1

Answer #1

Given that, regression equation is,

$\hat Y = -2X + 6$

If the X value is above the mean ( positive deviation) then,

the predicted Y value will be below the mean for the Y scores. ( Because coefficient of slope ( X ) is negative)
