(c) Use a calculator to verify that x = 5805, x² = 5,621,771, y = 586, y² = 67,290 and
xy = 559,673.
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.
O Given our value of r, y should tend to remain constant as x increases.
O Given our value of r, y should tend to increase as x increases.
O Given our value of r, we can not draw any conclusions for the behavior of y as x increases.
O Given our value of r, y should tend to decrease as x increases.

Can a low barometer reading be used to predict maximum wind speed of an approaching tropical cyclone? For a random sample of
tropical cyclones, let x be the lowest pressure (in millibars) as a cyclone approaches, and let y be the maximum wind speed (in
miles per hour) of the cyclone.
