      You can use this code, if you like, to get the data into SAS.

      Continue reading Chapter 5.  This begins a discussion of probability and will 
      not involve as much computer work.  Work problems 5.1 pg. 127 and 5.3, 5.4, 5.5 
      pg. 132.
      
      The test on Monday will involve comparisons, e.g. back-to-back stem and leaf

      (relative frequencies, marginal relative frequencies, conditional relative 
      frequencies) and exploratory regressions.  Also the SAS ideas we've gone over 
      in class will be fair game.
