Answer 1

Answer #1

Ans:

$\bar{X}=50$ , $\bar{Y}=268$ , r=0.335 , S_Y=39 & S_X=10

Regrassion equation of y on x : $Y-\bar{Y}=b_y_x(X-\bar{X})$

Now b_y_x=r(S_Y/S_X)

= 0.335(39/10)

= 1.3065

Therefore the equation: Y-268=1.3065(X-50)

Y=202.675+1.3065X

Therefore the intercept of the regrassion line is 202.7
