      •   In the dialog box => Enter 25.7% for the percent of the cases to be sampled  (about 20 cases for this data set).  Enter 50 for the number of samples to draw.  Now click ok.

      • This will generate a folder called Random Samples. Select this folder (click on it).Then  click edit and  click select all.  This will select all 50 samples.

      • Make sure mean is one of your summary statistics.  Perform the following windows commands.  Calc => Summaries => As Variables

      • This will generate a summary folder.  Select the variable labeled Mean(Summary1).  Now you can plot a histogram of this set of means and compare to the histogram for the original IQScores.

      • See bulletin message IQScoresSeventhGraders.  This message has an attachment with the data for problem 10.8.
