O positive negative (c) Use a calculator to verify that E(x) = 59, E(x2) = 919, E(y) = 638, E(y2) = 91,530, and E(x y) = 9,009. Computer. (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 increase as x increases. Given our value of r, y should tend to decrease 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 remain constant as x increases
