How many states have you been to, or been through? It doesn’t count to have flown over a state. (Graph the state data. Use Frequency polygon with at least 5 classes, but no more than 9 classes. Show your work in determining the class boundaries, limits, width and the frequency distribution. )

Solution: We are going to use 6 classes. The class width is computed as

Using these parameters we get the following table with the classes and the corresponding frequencies

This leads to the following frequency polygon:
