Question

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	977	924
y	40	100	65	145	78	153

(a) Make a scatter diagram of the data and visualize the line you think best fits the data.

(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

x = 5807,

x² = 5,625,235,

y = 581,

y² = 66,343

and

xy = 555,293.

Compute r. (Round your answer to three decimal places.)

As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer.

Given our value of r, y should tend to increase as x increases.

Given our value of r, y should tend to remain constant as x increases.

Given our value of r, y should tend to decrease as x increases.

Given our value of r, we can not draw any conclusions for the behavior of y as x increases.
