Answer to Question 1

The scatter diagram may suggest a non-linear relationship between the two variables. The correlation coefficient measures the strength of a linear relationship; therefore a value near zero indicates no linear relationship.

Answer to Question 2

A linear correlation coefficient of +0.095 indicates that there is very little or no linear correlation.
