8. Sand driven by wind creates large beautiful dunes at the Great Sahara Desert. 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). A test site at the Great Sahara Desert gave the following information about x and y. 70 115 105 82 93 125 88 3 45 21 7 16 62 12 (a) Construct a scatter diagram. (b) Suppose the computed value of r gives 0.949, what does the value tell you?
