Using your favorite statistics software package, you generate a scatter plot with a regression equation and correlation coefficient. The regression equation is reported as

y= −28.63x + 34.28

and the r= −0.79.

What proportion of the variation in y can be explained by the variation in the values of x?
r² = %

Report answer as a percentage accurate to one decimal place.
