Sand driven by wind creates large beautiful dunes at the Great Sand Dunes National Monument, Colorado. ... Is there a linear correlation between wind velocity and sand drift rate? Let x be a random variable representing wind velocity (in 10 cm/sec) and let y be a random variable representing drift rate of sand (in 100 g/cm/sec). The data are listed in the table below.
