\nAnswer:<\/p>\n
\nQuestion 2.
\nAccording to the histogram in Exercise 1, what fraction of the students surveyed spent 30-59 minutes on homework each night?
\nAnswer:<\/p>\n
\nIn the example above, how can you tell that \\(\\frac{1}{5}\\) of the people surveyed were in the 40-59 age group?

\nAnswer:<\/p>\n
\nStep 2: Along the vertical axis mark the scale. List the greatest and least numbers in the survey results Choose an interval. Label the axes.
\nStep 3: Graph the data by drawing bars of the correct height. Title the graph.

\nStep 4: Interpret the graph. Twice as many people were in the 20-39 age group as in the 0-19 age group. Most people were in the 20-39 age group.
\nThe group with the least number was the 60-79 age group.<\/p>\n
