Problem 30

Hurricanes The data in the next column represent the maximum wind speed (in knots) and atmospheric pressure (in millibars) for a random sample of hurricanes that originated in the Atlantic Ocean.

(a) Draw a scatter diagram treating atmospheric pressure as the explanatory variable.

(b) Compute the linear correlation coefficient between atmospheric pressure and wind speed.

(c) Does a linear relation exist between atmospheric pressure and wind speed?

Step-by-Step Solution:

Step 1 of 5) Hurricanes The data in the next column represent the maximum wind speed (in knots) and atmospheric pressure (in millibars) for a random sample of hurricanes that originated in the Atlantic Ocean. (a) Draw a scatter diagram treating atmospheric pressure as the explanatory variable. (b) Compute the linear correlation coefficient between atmospheric pressure and wind speed. (c) Do linear relationships exist between atmospheric pressure and wind speed Approach Step 1 Plot points for each year, with the date on the horizontal axis and the Partisan Conflict Index on the vertical axis.
