The data below are the average one-way commute times (in minutes) of selected students during a summerliterature class and the number of absences for those students for the term. Calculate the linear correlationcoefficient. $$\begin{array} { l | c | c | c | c | c | c | c | c | c | }
\text { Commute time (min), } \mathrm { x } & 71 & 84 & 90 & 89 & 87 & 97 & 74 & 99 & 79 \
\hline \text { Number of absences, } \mathrm { y } & - 1 & 3 & 6 & 6 & 4 & 11 & 0 & 11 & 1
\end{array}$$
A) 0.980
B) 0.890
C) 0.881
D) 0.819
