Solve the problem.
You obtain the multiple regression equation
= 2 + 6x
1 - 8x
2 from a set of sample data. Interpret the slope coefficients for x
1 and x
2.
◦ The slope coefficient of x
1 is
-6. This indicates that
will decrease 6 units, on average, for every 1-unit increase in x
1, provided that x
2 remains constant. The slope coefficient of x
2 is 8. This indicates that
will increase 8 units, on average, for every 1-unit increase in x
2, provided that x
1 remains constant.
