Compute the Linear Correlation Coefficient Between the Two Variables and Determine

Compute the linear correlation coefficient between the two variables and determine whether a linear relation exists.
- $\begin{array}{c|cccccccccc}\mathrm{x} & -12 & -10 & -3 & -6 & -8 & -9 & -7 & -5 & -4 & -11 \\\hline \mathrm{y} & -7 & -5 & 12 & 4 & 1 & -3 & 2 & 6 & 9 & -5\end{array}$

A) $\mathrm { r } = 0.990$ ; linear relation exists
B) $\mathrm { r } = 0.881$ ; no linear relation exists
C) $\mathrm { r } = 0.819$ ; linear relation exists
D) $\mathrm { r } = 0.792$ ; no linear relation exists
