|
|
False
|
|
|
Either A or B

|
|
None of the above

Explanation:
Detailed explanation-1: -ŷ = b0 + b1x where: b0 is a constant, b1 is the regression coefficient, x is the value of the independent variable, and ŷ is the predicted value of the dependent variable.
Detailed explanation-2: -b1 = the regression coefficient representing the change in y produced by each unit change in X1. In other words, this represents the effect of X1 on y. b2 = the regression coefficient representing the change in y produced by each unit change in X2. In other words, this represents the effect of X2 on y.
