Answer #1

Ans 2 ) a ) the equation is called the Multiple linear regression equation.

Ans b ) there is one dependent and 4 independent variable

Ans c ) 0.286 is called the coefficient of mechanical aptitude score.

Ans d ) 0.002

Ans e ) y = =11.6+0.4*6+0.286*280+0.112*97+0.002*35

performace of new machine = 105.014
