Answer:
-0.2789
Step-by-step explanation:
The Correlation Coefficient can be calculated with the following formula
[tex]r=\frac{Cov(X,Y)}{Var(X)Var(Y)}[/tex]
or
[tex]r=\frac{n \sum XY-(\sum(X)\sum(Y)}{\sqrt{[n\sum X^2-(\sum X)^2][n\sum Y^2-(\sum Y)^2]}}[/tex]
We can do the auxiliary calculations in excel and replace in the formula
[tex]r=\frac{4\times59-(17\times19)}{\sqrt{[4 \times 95-(17)^2][4\times69-(15)^2]}}=-0.2789[/tex]
