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.x: 1004 975 992 935 979 920y: 40 100 65 145 83 153

(b) Would you say the correlation is low, moderate, or strong? O low O moderate strong Would you say the correlation is positive or negative? positive O negative (c) Use a calculator to verify that \\ x = 5805, \\ x - 5,621,771, \\ y - 586, \\y - 67,148 and xy = 559, 732. 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, y should tend to decrease as x increases. O Given our value of r, y should tend to remain constant as x increases. O Given our value of r, we can not draw any conclusions for the behavior of y as x increases
