Regression and Forecasting Models
... c. If the correlation is positive the slope of the regression is also positive. d. If the true correlation were actually zero, there is only a .001 probability that the observed value could be as high as .68. .68 would be very unlikely. e. R2 = .4624. This would be the R2 if y were regressed on x. ...
