10. Determine whether the scatter diagram indicates that a linear relation may exist betw10. Determine whether the scatter diagram indicates that a linear relation may exist between the two variables. If the relation is linear, determine whether it indicates a positive or negative assoication between the variables?

14. Match the linear correlation coef?cient to the scatter diagram. The scales on the x- and y-axes are the same for each diagram.

(a) r = -0.969         (b) r = -0.049         (c) r = -1         (d) r = -0.992ssociation between the variables.

Solution

10. It is Negative COrrelation between the variables
14.
-0.969 Since the points are slightly adjacent to eacch other & nt in a single plane
