Angelo used a radar gun to take a sample of the speeds of cars on the road in front of his house. The results are below.

{57,53,53,71,73,57,61,58,78,

64,54,69,56,58,49,56,53,

52,82,62,61,60,71,75,60}

• Use the results of Angelo's sample to draw the following graphs by hand:
• A stem-and-leaf plot,
• A histogram with 5 classes,
• A box plot.
• Be sure your graph is neat by using a straight edge for all lines.
• Use a ruler for even spacing on the axes.
• Don't forget to include a title and axis labels.
• Scan or take a picture of your work.You will upload your graphs in the next question.
