Question

If the lines of regression yon x is 8x –10y+66 = 0 and x on y is
40x –18y-214= 0 The value of variance of x is 9. The standard deviation of x
is​

Answer 1

Answer:

To find given regression equation in such a way that the coefficient of dependent variable is less than one at least in one equation.

so, 8x+10y=−66⇒10y=66+8x⇒y=1066+108x

That is byx=8/10=0.8
