The Answer of $\begin{array}{c|c|c|c|c|l}
\overline{\mathrm{x}} & \mathrm{s}_{\mathrm{x}} & \overline{\mathrm{y}} & \mathrm{s}_{\mathrm{y}} & \mathrm{r} & \hat{\mathrm{y}}=\mathrm{b}_{0}+\mathrm{b}_{1 \mathrm{x}} \
\hline 3 & 0.05 & 7.4 & 2.0 & -0.6 & \hat{\mathrm{y}}=?
\end{array}$
A) $\hat{y}$ = 79.40 - 24.00x
B) $\hat{y}$ = 40.00 + 2.47x
C) $\hat{y}$ = -24.00 + 79.40x
D) $\hat{y}$ = -112.60 + 40.00x
E) $\hat{y}$ = 7.45 - 0.01x

A) y^\hat{y}y^​ = 7940 - 24 y^\hat{y}y^​ = 4000 + 2 y^\hat{y}y^​

A) $\hat{y}$ = 7940 - 24 $\hat{y}$ = 4000 + 2 $\hat{y}$
