(b) Use a calculator to verify that Ex = 150.4, Ex² = 3251.86, Ey = 250, Ey² = 10630 and Exy = 5484.8. Compute r. (Round your answer to four decimal places.) As x increases, 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 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. Given our value of r, y should tend to increase as x increases.
