You run a regression analysis on a bivariate set of data (n=56). You obtain the regression equation

y=1.559x+11.638

with a correlation coefficient of r=0.506 (which is significant at α=0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 80 on the response variable.


What is the predicted explanatory value?
