Question

What is the correlation coefficient with the following data points: (2,47), (3,2), (5,26)?

0.19
-0.29
0.29
-0.19

Answer 1

The second one is the answer

Answer 2

Option B (-0.29)

Explanation:

Given are x,y values as

(2,47), (3,2), (5,26)

x y xy x^2 y^2

2 47 94 4 2209

3 2 6 9 4

5 26 130 25 676

Total 10 75 230 38 2889

Cov -6.666666667

r -0.2907

Thus we find correlation coefficient is -0.29

Option B is right
