*First at all the p-value that most of the package show for each coefficient must be smaller that 0.05 for 95% confidence, or check for signifficance and conficence interval for the slope.
* You can check for signifficance of the sample correlation coefficient.
* Conficence interval for population Correlation Coefficient
* Test for linearity of Regression.ref: STATISTICS by Crow/Davis/Maxfield ed. COLES
