The processing of raw coal involves "washing," in which coal ash (nonorganic, incombustible material) is removed. A study provides data relating to the percentage of ash to the volume of a coal particle. The average percentage of ash for six volumes of col particles was measured. Results are as follows: b) Volume (cm2) Percent Ash 0.01 3.32 0.06 0.58 2.24 15.55 276.02 4.05 5.69 7.06 8.17 9.36 Compute the least-squares line for predicting percent ash (y) from volume (x). Plot the residuals versus the fitted values. Does the linear model seem appropriate? Explain. Compute the least-squares line for predicting percent ash from In volume. Plot the residuals versus the fitted values. Does the linear model seem appropriate? Explain.
