Extracted text: (b) Would you say the correlation is low, moderate, or strong? positive or negative? O moderate and negative O strong and negative O strong and positive O moderate and positive O low and negative O low and positive (c) Use a calculator to verify that Ex = 139, Ex? = 7359, Ey = 150, Ey2 = 4798, and Exy = 3193. 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 increase as x increases. O Given our value of r, y should tend to decrease as x increases. O Given our value of r, we cannot draw any conclusions for the behavior of y as x increases. O Given our value of r, y should tend to remain constant as x increases.
