Answer
$\approx0.18$
Work Step by Step
$\sum x=16$, $\sum y=36$, $\sum xy=133$, $\sum x^2=64$, $\sum y^2=286$ $n=5$(the number of data points)
Thus the correlation coefficient is: $\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{n(\sum x^2)-(\sum x)^2}\sqrt{n(\sum y^2)-(\sum y)^2}}=\frac{5(133)-(36)(18)}{\sqrt{5(64)-(16)^2}\sqrt{5(286)-(36)^2}}\approx0.18$ where
