1. Devore and Peck [11, Exercise 13.62,] describe an experiment to determine the effect of oxygen concentration on fermentation end products. Four oxygen concentrations and two types of sugar were used. The data are

   (def ethanol (list .59 .30 .25 .03 .44 .18 .13 .02 .22 .23 .07
                      .00 .12 .13 .00 .01))
   (def oxygen (list 1 1 1 1 2 2 2 2 3 3 3 3 4 4 4 4))
   (def sugar (list 1 1 2 2 1 1 2 2 1 1 2 2 1 1 2 2 ))
   

   and are on file the oxygen.lsp. Use a scatterplot matrix to examine these data.
2. Use scatterplot matrices to examine the data in the examples and exercises of Section 6.1 above.
