The following is a frequency data set for test scores in a small class. Construct a cumulative frequency plot displaying the data on your own paper, calculator, or StatCrunch. Then, describe the the graph in a sentence or two. Be sure to communicate in your answer how to create the graph (be sure to include what the cumulative frequencies are)
Test scores:
40-49 : 1
50-59 : 2
60-69 : 2
70-79 : 7
80-89 : 9
