Question
Can a low barometer reading be used to predict maximum wind speed of an approaching tropical cyclone? 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. Suppose a random sample of cyclones gave the following information.

 

x

1014

935

980

955

995

y

50

80

60

135

84


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

  
Since r is positive, as x increases, y increases.
 
 
  
Since r is positive, as x increases, y remains the same.
 
 
  
Since r is negative, as x increases, y decreases.
 
 
  
Since r is zero, as x increases, y increases.

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. Suppose a random sample of cyclones gave the
following information.
X

As x increases, does the value of imply that y should tend to increase, decrease, or remain
the same? Explain.
Sincer is positive, as x increases, y increases.
Sincer is positive, as x increases, y remains the same.
Sincer is negative, as x increases, y decreases.
Sincer is zero, as x increases, y increases.
