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.

Question

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.

The following is a chart of baseball players' salaries and statistics from 2016.

Brandon Crawford	84	12	6.000
Rajai Davis	48	12	5.950
Aaron Hill	38	10	12.000
Coco Crisp	55	13	11.000

Jorge Soler	31	12	3.667
Evan Gattis	72	32	3.300
Logan Forsythe	52	20	2.750
Jean Segura	64	20	2.600

So you don't have to type all the data into the Reg2 sheet, you can copy the entire table and paste it into the Reg3 sheet or a new sheet. Then copy just the rows you need from the Reg3 sheet or the new sheet and paste them into the Reg2 sheet.

a) Find the multiple linear regression equation. Enter the coefficients rounded to 4 decimal places.
ˆy=y^= + x1x1 + x2x2

b) Use the multiple linear regression equation to predict the salary for a baseball player with an RBI of 30 and HR of 21. Round your answer to 1 decimal place, do not convert numbers to dollars.
