We wish to predict the salary for baseball players (yy) using the variables RBI (x1x1) and HR (x2x2), then we use a regression equation of the form ˆy=b0+b1x1+b2x2y^=b0+b1x1+b2x2.

HR - Home runs - hits on which the batter successfully touched all four bases, without the contribution of a fielding error.
RBI - Run batted in - number of runners who scored due to a batters's action, except when batter grounded into double play or reached on an error
Salary is in millions of dollars.
