Solution
WebAssign. Graphing Tool
(b) Would you say the correlation is low, moderate, or strong? positive
or negative?
o low and positive
O strong and negative
o moderate and positive
O low and negative
o moderate and negative
O strong and positive
(c) Use a calculator to verify that Ex = 135, Ex² = 6783, Ey = 148,
Ey2 = 4690, and Exy = 3045. Compute r. (Round your answer to three
decimal places.)

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