Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary.
-Managers rate employees according to job performance and attitude. The results for several randomly selected employees are given below.
$\begin{array}{cc|c|c|c|c|c|c|c|c|c}
\text { Performance } & 59 & 63 & 65 & 69 & 58 & 77 & 76 & 69 & 70 & 64 \
\hline \text { Attitude }& 72 & 67 & 78 & 82 & 75 & 87 & 92 & 83 & 87 & 78
\end{array}$

A) $\hat { y } = 2.81 + 1.35 x$
B) $\hat { y } = 92.3 - 0.669 \mathrm { x }$
C) $\hat { y } = 11.7 + 1.02 x$
D) $\hat { y }= - 47.3 + 2.02 \mathrm { x }$
