A practice document using the “USArrests” data.

So here is where I’d have lots of things to say and such. So this is where we add text, lets emphasize that if we are not too bold.

We could also look at how the scatter plots above are showing the correlation coefficient. \[ \begin{align} \rho(X,Y) = \frac{Cov(X,Y)}{Var(X)\cdot V(Y)} \end{align} \]

And the cool thing is, the math worked out quite well
