(b) Use a calculator to verify that Ex = 149.6, Ex2 = 3,220.10, y = 244, Zy2 = 9,834 and 2xy = 5,290.7. Computer. (Round your answer to four decimal places.) r= 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 remain constant as x increases. 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.
