(b) Would you say the correlation is low, moderate, or strong? Olow Omoderate strong Would you say the correlation is positive or negative? O positive O negative (c) Use a calculator to verify that Σ× = 64, Σx = 1154, Σy = 640, Σy = 91,750, and Exy = 9,870. Compute r. (Round your answer to four decimal places.) As x increases from 3 to 26 months, does the value of r imply that y should tend to increase or decrease? Explain your answer. OGiven our value of r, y should tend to decrease as x inc ases. O Given our value of r, we can not 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.
