An indoor running track is 200 meters in length . During a 3,000 -meter race , runners must complete 15 laps of the track. An electronic timing device records the time it takes each runner to complete a lap in the race . These are called lap times . The histogram below displays the lap times for Stefano, a runner in the 3,000.meter race

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.
