Find the best predicted value of y corresponding to the given value of x.
-Ten pairs of data yield $\mathrm { r } = 0.003$ and the regression equation $\hat { \mathrm { y } } = 2 + 3 \mathrm { x }$. Also, $\overline { \mathrm { y } } = 5.0$. What is the best predicted value of $y$ for $x = 2$ ?
A) $5.0$
B) $8.0$
C) $17.0$
D) $7.0$

The best predicted value of y for x = 2 is 8.0. This is because the regression equation is $\hat { \mathrm { y } } = 2 + 3 \mathrm { x }$, so when x = 2, $\hat { \mathrm { y } } = 2 + 3(2) = 8$.
