Let x be the average number of employees in a group health insurance plan, and let y be the average administrative cost as a percentage of claims.x: 3 7 15 31 71y: 40 35 30 27 17

(b) Would you say the correlation is low, moderate, or strong? positive or negative? strong and negative O moderate and negative O low and negative O moderate and positive O low and positive strong and positive (c) Use a calculator to verify that Ex = 127, Ex?= 6285, Ey = 149, Ey2 = 4743, and Exy = 2859. 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. Given our value of r, y should tend to increase as x increases. Given our value of r, y should tend to remain constant as x increases. Given our value of r, we cannot draw any conclusions for the behavior of y as x increases. Given our value of r, y should tend to decrease as x increases
