Total points in a board game based on the average number of hours played is predicted using the least-square regression line, 9 = 280.3 + 85.7%, where ý represents the total points scored and x represents the average number of hours spent playing the game. A player plays the game for an average of 3 hours and has a point total of 550. What is the residual for the player? (3

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 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, 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 decrease as x increases.
