Throughout the world, natural ocean beaches are beautiful sights to see. If you have visited natural beaches, you may have noticed that when the gradient or dropoff is steep, the grains of sand tend to be larger. In fact, a man-made beach with the “wrong” size granules of sand tends to be washed away and eventually replaced when the proper size grain is selected by the action of the ocean and the gradient of the bottom. Since man-made beaches are expensive, grain size is an important consideration. In the data that follow, of granules of sand, and on natural ocean beaches. x y 0.17 0.63 0.19 0.70 0.22 0.82 0.235 0.88 0.235 1.15 0.30 1.50 0.35 4.40 0.42 7.30 0.85 11.30 Find the sample mean and standard deviation for x and y.
