Answer #1

(a) The regression output is :-

     SUMMARY OUTPUT Regression Statistics Multiple R 0.751941946 R Square 0.56541669 Adjusted R Square 0.514289242 Standard Error

Therefore,

\textup{R/IP=(0.5543)+(-0.2506)SO/IP+(0.9138)HR/IP}

R^2=0.5654

R_{a}^2=0.5143

(b) The data is able to explain 51.43% of the variability .

(c) The output is :-

1596240809671_blob.png

Therefore,

\textup{ERA=(3.991)+(-1.8439)SO/IP+(11.1775)HR/IP}

R^2=0.6159

R_{a}^2=0.5707

The fit is not bad.... ..... the data is able to explain 57.07% of the variability .
