Final answer:
To construct a histogram for speed limits: determine intervals, count frequencies, plot the histogram, and scale the axes.
Step-by-step explanation:
Constructing a Histogram for Speed Limits:
1. Determine the intervals: Divide the range of speed limits into five to six equal intervals. For example, if the range is 0 to 100, each interval could be 20 (0-19, 20-39, 40-59, 60-79, 80-99, and 100).
2. Count the frequencies: Count the number of speed limits that fall into each interval.
3. Plot the histogram: On the x-axis, mark the intervals, and on the y-axis, mark the frequencies. Draw rectangles above each interval, with the height of each rectangle representing the frequency. Use a ruler and pencils to sketch the graph accurately.
4. Scale the axes: Choose appropriate scales for the x-axis and y-axis based on the range of speed limits and frequencies. Make sure the graph fits within the provided space.
