Complete Question

The complete question is shown on the first uploaded image

Answer:

The coefficient is $r =0.81$

Step-by-step explanation:

From the question we are told that

$cov(x, y )= 1260$

$s_x^2 = 1600$

$s_y^2 = 1225$

Generally the coefficient of determination is mathematically represented as

$r = [ \frac{cov(x,y)}{ \sqrt{s_x^2} * \sqrt{s_y^2} } ]^2$

substituting values

$r = [ \frac{ 1260}{ \sqrt{1600} * \sqrt{1225} } ]^2$

$r =0.81$
