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 975 992 935 989 922 y 40 100 65 145 84 153             (c) Use a calculator to verify that         x = 5817,          x2 = 5,645,135,          y = 587,          y2 = 67,315 and         xy = 561,857.
