You run a regression analysis on a bivariate set of data (n 25). You obtain the regression equation %3D y = -0.405x + 27.472 0.638 (which is significant at a = with a correlation coefficient of r = 0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 40 on the response variable. What is the predicted explanatory value?
