Hello Sam,

    I am having trouble preparing all the details of how to do the
last sentence of both 
                         13.1 (bedrooms and home cost)
                     and 13.2 (beer and blood alcohol).

    13.1 Remove the last sentence from what is due tomorrow.
         You only need to do the scatterplot and the fitted
         regression line.

         Skip the last sentence!

         "On the same graph, test the hypothesis that an extra
          bedroom costs $60,000 against the alternative that
          it costs more."   THIS LAST SENTENCE is NOT DUE
                            tomorrow.  SKIP IT!

    13.2  Same as 13.1 above here.  SKIP THE LAST SENTENCE for now.

          "Test the hypothesis that another beer raise your BAL
           by 0.02 percent against the alternative that it is less."

           SKIP the above sentence, the last sentence.
           Just do the scatterplot and fit the regression line.

     We will get to those R techniques in class tomorrow or
     next week and give you some theory, practice and 
     more R background first!

Mark
