Help me answer part B&C
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 y 1004 975 992 935 985 928 40 100 65 145 77 148 LAUSE SALT (a) Make a scatter diagram of the data and visualize the line you think best fits the data. 140 1000 140 1000 120 120 980 980 100 100 so 960 960 80 60 940 60 940 40 40 80 100 120 140 940 950 960 970 580 990 1000 950 960 970 960 990 1000 xdlowest pressure (in millibars)) xdowest pressure (in millibars)) x (lowest pressure (in millibars)) Ⓡ (b) Would you say the correlation is low, moderate, or strong? low moderate strong Would you say the correlation is positive or negative? positive negative (c) Use a calculator to verify thatx=5819,x2= 5,648,339, y=575,264,683 and xy = 550,904.
