0.929

-0.863

None of the choices

Data on the number of cancer deaths among Americans (in 1,000s) and years (since 2001) result in the
regression line: Deaths = 550 – 6.05(Years) with r2
= 0.745.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
