Answer
(a).
Work Step by Step
$R^2=57.9\%=0.579$, the correlation is the positive or negative square root of $R^2$.
We can find the slope $b$ in the row "appraised" and the column "Coeff," thus $b=1.2103\gt0$.
$b\gt0$, thus the correlation is positive, thus $r=\sqrt{0.579}\approx0.761$, thus the answer is (a).
