Linear Regression and Correlation: Testing the Significance of the Correlation Coefficient: Corrected conclusions.  Updated formatting and language.

Linear Regression and Correlation: Testing the Significance of the Correlation Coefficient: Corrected one typo.

Linear Regression and Correlation: Testing the Significance of the Correlation Coefficient:Updated summary.

Linear Regression and Correlation: Testing the Significance of the Correlation Coefficient: In Assumptions, minor correction.

Linear Regression and Correlation: Testing the Significance of the Correlation Coefficient: Changed name from "Facts about the Correlation Coefficient." Includes a hypothesis test that tests whether r is significant or not.

Linear Regression and Correlation: Testing the Significance of the Correlation Coefficient: Added the hypothesis test to determine whether r is significant or not.

Regression and Correlation: Facts About the Correlation Coefficient for Linear Regression:  Changed (regression) line to (regression line).

 Linear Regression and Correlation: Facts About the Correlation Coefficient for Linear Regression:  Added information about the Coefficient of Determination.

Linear Regression and Correlation: Facts About the Correlation Coefficient for Linear Regression:  For clarity, changed the NOTE that occurs in the section into four sentences so that the sentence that follows ("Can the line be used for prediction?") makes more sense.
