O positive O negative (c) Use a calculator to verify that x= 5813, x - 5,637,239, Sy = 585, = 66,707 and xy = 559,677. 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 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 remain constant as x increases. O Given our value of r, y should tend to decrease as x increases.

Transcribed Image Text: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.
