Solved

In the First-Order Model y~=50+25x1−10x2−6x1x2\tilde { y } = 50 + 25 x _ { 1 } - 10 x _ { 2 } - 6 x _ { 1 } x _ { 2 }

Question 67

True/False

In the first-order model y~=50+25x1−10x2−6x1x2\tilde { y } = 50 + 25 x _ { 1 } - 10 x _ { 2 } - 6 x _ { 1 } x _ { 2 } ,a unit increase in x2,while holding x1 constant at a value of 3,decreases the value of y on average by 3 units.
