Question

[62] If mean of x and:y variables is 20
and 40 respectively and the
regression coefficient of y on x is
-1.608, then the regression line of y.
on x is
(a) y = 1.608x + 7.84
(b) y = 1.5x + 4.84
(c) y = 1.608x + 4.84
: (d) y = 1.56x + 7.84

Answer 1

Answer:

y=1.608 x+7.84

Step-by-step explanation:

(y- mean of y)=byx (x-mean of x)

y-40=1.608(x-20)

y-40=1.608 x - 1.608*20

y-40=1.608 x - 32.16

y=1.608 x + 40 - 32.16

y = 1.608 x + 7.84 (ans)
