It is given that X =10, Y =90, _X=3, _Y=12 and r _ XY =0.8 . The regression equation of X on Y is

Options

  1. AY =3.2 X +58
  2. BX =3.2 Y +58
  3. CX =-8+0.2 Y
  4. DY =-8+0.2 X

Correct answer

C. X =-8+0.2 Y

Step-by-step solution

X =10, Y =90, _ x =3, _ y =12, r _ xy =0.8 Regression equation x on y is x-10=r _x _y (y-90) aligned & x -10=0.8 3 12 ( y -90) & x -10= 2.4 12 ( y -90) aligned aligned & x-10=0.2(y-90) & x-10=0.2 y-18 & x=0.2 y-8 . aligned
