The Answer is

\begin{array} { l } S S _ { x y } = 45.1 - \frac { ( 21 ) ( 9.9 ) } { 5 } = 3.52 ; S S _ { x x } = 99 - \frac { ( 21 ) ^ { 2 } } { 5 } = 10.8 ; \S S _ { y y } = 20.79 - \frac { ( 9.9 ) ^ { 2 } } { 5 } = 1.188 ; r = \frac { 3.52 } { \sqrt { 10.8 \cdot 1.188 } } \approx .9827 ;\end{array}

There is a strong linear relationship between

x

and

y

.
