Solved

In the First-Order Model y~=75−12x1+5x2−3x1x2\tilde { y } = 75 - 12 x _ { 1 } + 5 x _ { 2 } - 3 x _ { 1 } x _ { 2 }

Question 60

True/False

In the first-order model y~=75−12x1+5x2−3x1x2\tilde { y } = 75 - 12 x _ { 1 } + 5 x _ { 2 } - 3 x _ { 1 } x _ { 2 } ,a unit increase in x1,while holding x2 constant at a value of 2,decreases the value of y on average by 8 units.
