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 40 100 992 935 979 65 145 82 154 920 A USE SALT (a) Make a scatter diagram of the data and visualize the line you think best fits the data. 160. * 140 120 100 80 60 40t. 920 940 960 980 1000 x (lowest pressure (in millibars)) 160 140 120 100 80 60 E 40le 920 940 960 980 1000 x (lowest pressure (in millibars)) 1000 980 960 940 920. 40 60 80 100 120 140 x (lowest pressure (in millibars)) 1000 980 960 940 920 40 60 80 100 120 140 x (lowest pressure (in millibars)) (b) Would you say the correlation is low, moderate, or strong?

A 1982 paper by Hans Rosendal and Samuel Shaw established a correlation between the maximum sustained surface wind speeds to the minimum sea level pressure in central north pacific cyclones. Use the following data below to test this result.

Round to three decimals Find the equation of the regression line. Round each value to two decimals Preview New data has just arrived indicating that the minimum sea level pressure for a storm is 955 millibars. Predict the maximum sustained wind speed in knots. Round your answer to the nearest integer

"Live Tree and Tree-Ring Records to Reconstruct the Structural Development of an Old-Growth Douglas Fir/Western Hemlock Stand in the Western Washington Cascades." Corvallis, OR: Forest Science Data Bank, 2005. (a) Obtain a point estimate for the mean and standard deviation diameter of a Douglas fir tree in the western Washington Cascades. (b) Because the sample size is small, we must verify that the data come from a population that is normally distributed and that the data do not contain any outliers. The figures show the normal probability plot and boxplot. The correlation between the tree diameters and expected z-scores is 0.982. Use Option 1 or Option 2 to determine if the…

A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation.
