You want 10 classes with a "nice" class width. A "nice" class width would be a multiple of 5 or 10. Your classes should be labeled using interval notation. Since the data appears to be discrete, use a closed-interval to label each class. Each class should contain its lower class limit, and the lower class limits should all be mu iples of the class width. (Note: interval notation for closed intervals will take the following form "[number,number]") Data range Frequency
