Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary.
-$\begin{array}{r|rrrrr}
\mathrm{x} & 3 & 5 & 7 & 15 & 16 \
\hline \mathrm{y} & 8 & 11 & 7 & 14 & 20
\end{array}$

A) $\hat { y } = 5.07 + 0.753 \mathrm { x }$
B) $\hat { y } = 5.07 + 0.850 x$
C) $\hat { y }= 4.07 + 0.850 x$
D) $\hat { y }= 4.07 + 0.753 x$
