### HW3 Problem 1 RStudio a) b) ## HW3 Correlations and Linear Regression Can a low barometer reading be used to predict maximum wind speed of an approaching tropical cyclone? Data for this problem are based on information taken from Weatherwise (Vol 46, No 1), a publication of the American Meteorological Society. 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 | 985 | 932 | |----:|:------:|:----:|:----:|:----:|:----:|:----:| | y | 40 | 100 | 65 | 145 | 80 | 150 |

a) Make a scatter diagram and draw the line you think best fits the data.

b) Would you say the correlation is low, moderate, or strong? positive or negative?
