Use the Random Digits Table to select a simple random sample of 5 words from the Gettysburg Address. Do this by starting in the table at any point (it does not have to be at the beginning of a line) and reading off the first 5 three-digit numbers that you come across. (When you get a number greater than 268, skip it and move on. If you happen to get repeats, keep going until you have 5 different numbers between 001 and 268.) Record the random digits that you selected, the corresponding words, and the lengths (number of letters) of the words:
