You run a regression analysis on a bivariate set of data (n=71n=71). You obtain the regression equationy=−1.154x−8.512y=-1.154x-8.512with a correlation coefficient of r=−0.604r=-0.604 (which is significant at α=0.01α=0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 140 on the response variable.
