Choose File No file chosen This answer has not been graded yet. (b) Would you say the correlation is low, moderate, or strong? O low moderate strong Would you say the correlation is positive or negative? positive O negative (c) Use a calculator to verify that E(x) = 57, E(x2) = 855, E(y) = 624, E(y2) = 86,566, and E(x y) = 8,415. Compute r. (Enter a number. Round your answer to three decimal places.) As x Increases from 3 to 21 months, does the value of r imply that y should tend to Increase or decrease? Explain your answer. Given our value of r, y should tend to remain constant as x Increases. 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 decrease as x increases. Given our value of r, y should tend to Increase as x increases. 80OF
