In the First-Order Model $\tilde { y } = 50 + 25 x _ { 1 } - 10 x _ { 2 } - 6 x _ { 1 } x _ { 2 }$

question 67

True/False

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