    The vertical axis shows how many people responded for each bar.

  2. How many classmates have eight or nine people at home for dinner?

    Which bar shows eight or nine people at home for dinner?

    The vertical axis reading for the bar is 1, so in other words, one classmate has eight or nine people at home for dinner.

  3. Can you tell which is the most common number of people at home for dinner? Why or why not?
