Create a frequency distribution starting with a lower class limit of zero and a class width of 40.

Set up a relative and a cumulative frequency distribution. The relative frequency distribution may be added as an additional column to your frequency distribution. The cumulative frequency must be its own separate chart! It cannot be added.

What would be the class width if you wanted 12 classes?

Sketch a histogram and a relative frequency polygon. (These two charts can be part of a single sketch. Use color if you can! Note that the labeling of the axis for the frequency polygon is different from that of the histogram. Color would really help to distinguish them)
