40.3 Diesel Fuel. Four diesel fuels were tested to estimate the partition coefficient Kdw of eight organic compounds as a function of their solubility in water (S). The compounds are (1) naphthalene, (2) 1-methyl-naphthalene, (3) 2-methyl-naphthalene, (4) acenaphthene, (5) fluorene, (6) phenanthrene, (7) anthracene, and (8) fluoranthene. The table is set up to do linear regression with dummy variables to differentiate between diesel fuels. Does the partitioning relation vary from one diesel fuel to another?
