Solved

In the First-Order Model y~=60+40x1−10x2+5x1x2\tilde { y } = 60 + 40 x _ { 1 } - 10 x _ { 2 } + 5 x _ { 1 } x _ { 2 }

Question 83

True/False

In the first-order model y~=60+40x1−10x2+5x1x2\tilde { y } = 60 + 40 x _ { 1 } - 10 x _ { 2 } + 5 x _ { 1 } x _ { 2 } ,a unit increase in x2,while holding x1 constant at 1,changes the value of y on average by -5 units.
