What is the average length of the words in a book? A sample of ten words was randomly selected from a 304-page book and the average length (measured in letters) of the ten words was calculated. This process was repeated 15 times. The average word length of each of these fifteen samples is shown in the table below and in the histogram below. Use this information to answer the following questions.
