Question

Given

ID	X	Y
A	10	15
B	4	5
C	13	16
D	7	9
E	13	4
F	1	5

What is the variation in Y that can be explained by X? please explain

A) 50.7

B) 22.7

C) 36.3

D) 105.7

E) 91.3

Answer 1

Here we will find R-square to see the variation in Y that can be explained by X

so let's find R-square

Now R-square = r2 = (0.506)2

R-square = 0.2560

So 25.60% variation in Y that can be explained by X

But here the option may be

B) 22.7
