(c) Use a calculator to verify that Σx = 131, Σx2 = 6479, Σy = 153, Σy2 = 4895, and Σxy = 3257. Compute r.
r =

As x increases, does the value of r imply that y should tend to increase or decrease? Explain.
Given our value of r, y should tend to decrease as x increases.
Given our value of r, we cannot draw any conclusions for the behavior of y as x increases.
Given our value of r, y should tend to remain constant as x increases.
Given our value of r, y should tend to increase as x increases.
