Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is
contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters,
for a sample of 6 adults. The following table presents the results.

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.
