Suppose a multiple regression model is given by y = - 4.09x1 + 8.59x, -23.91. What would an interpretation of the coefficient of x1 be? Fill in the blank below An interpretation of the coefficient of x1 would be, if x1 increases by 1 unit, then the response variable will decrease by units, on average, while holding x2, constant Solution -4.09 Units as the Equations has the constant multipled -4.09 to x1 units.
