Ocessing of raw coal involves "washing," in which coal ash (nonorganic, incombustible material) is removed. the article "quantifying sampling precision for coal ash using gy’s discrete model of the fundamental error" (journal of coal quality, 1989: 33–39) provides data relating the percentage of ash to the volume of a coal particle. the average percentage of ash for six volumes of coal part was measured, and represented below: volume (cm3) 0.01 0.06 0.58 2.24 15.55 276.02% ash 3.32 4.05 5.69 7.06 8.17 9.36compute the least square line for predicting percent ash from in volume.
