Using multiple regression, the relationship of y to four other variables was established as: y = 12 + 3x₁ – 5x₂ + 7x₃ + 2x₄ when x₁ increases 2 units and x₂ increases 1 unit, while x₃ and x₄ remain unchanged, using this model what change would you expect in your estimate of y?

The estimate of Y changes by -2 or decreases by 2.

Step-by-step explanation:

We are given the following information:

Using Multiple regression, the relationship of Y to four other variables was established as:

increases 2 units and increases 1 unit, while and remain unchanged.

Predicted Y =

Change in Y =

The estimate of Y changes by -2 or decreases by 2.
