The multiple regression equation y = 5- 7x, + 2x2 is obtained from a set of sample data. Interpret the slope coefficients for x, and *2 ()A. The slope coefficient of x, is 2. This indicates that y will increase 2 units. on average. for every 1-unit increase in x,, provided that x2 remains constant. The slope coefficient of x2 is - 7. This indicates that y will decrease 7 units, on average, for every 1-unit increase in X2. provided that x, remains constant. O B. The slope coefficient of x, is 7. This indicates that y will increase 7 units, on average, for every 1-unit increase in x1. provided that x2 remains constant. The slope coefficient of x2 is - 2. This indicates that y will decrease 2 units, on average, for every 1-unit increase in x2. provided that x, remains constant. C. The slope coefficient of x, is - 2. This indicates that y will decrease 2 units, on average. for every 1-unit increase in x1. provided that x2 remains constant. The slope coefficient of *2 is 7. This indicates that y will increase 7 units, on average, for every 1-unit increase in x2. provided that x, remains constant D. The slope coefficient of x, is - 7 This indicates that y will decrease 7 units, on average, for every 1-unit increase in x1. provided that x2 remains constant The slope coefficient of x2 is 2. This indicates that y will increase 2 units, on average, for every 1-unit increase in x2 provided that x, remains constant
