Chemical engineers at Tokyo Metropolitan University analyzed urban air specimens for the presence of low molecular weight dicarboxylic acid (Environmental Science & Engineering, Oct. 1993). The dicarboxylic acid (as a percent of total carbon) and oxidant concentrations for 19 air specimens collected from urban Tokyo are listed in the table on below. Consider a straight line model relating dicarboxylic acid percentage (y) to oxidant concentration (x). Conduct a complete residual analysis.
