Column one is the midpoint of the brackets that you have chosen.  Column two is the name of the groups.  Column three is the number of individuals within each bracket.  Copy and paste the following into the SAS Editor Untitled1 window, then copy and paste your data into the yellow area from an Excel spreadsheet, and change the names (if desired) of the data name, input name, and tables name (make sure the last two match). Then you are ready for the running man!
