O positive O negative (c) Use a calculator to verify that x = 58, x² = 914, Ly = 648, v² = 94,842, and xy = 9,073. Compute r. (Round your answer to four decimal places.) As x increases from 3 to 23 months, does the value of r imply that y should tend to increase or decrease? Explain your answer. O Given our value of r, y should tend to increase as x increases. O Given our value of r, we can not 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. O Given our value of r, y should tend to decrease as x increases.
