Based on the following table, create a bar chart that is divided into 5 equally sized classes.

Start by defining five equal classes and determine the class boundaries. Using these classes, we can calculate how many numbers fall into each class. Create a frequency table from this information and then generate a graphical bar chart. The bar chart illustrates the distribution of incomes for residents across different classes.
