molecular-weight dicarboxylic acid (Environmental Science & Engineering, Oct. 1993). The dicarboxylic acid (as a percentage of total carbon) and oxidant concentrations for 19 air specimens collected from urban Tokyo are listed in the table above. SAS printouts for the straight-line model relating dicarboxylic acid pcrcentage (y) to oxidant concentration (x) are also provided on pages 619-621. Conduct a complete residual analysis.
