The cumulative frequency and the cumulative relative frequency for a given class interval are the sums of the frequencies and relative frequencies, respectively, over all classes up to and including the given class. For example, if there are five classes, with frequencies 11, 7, 3, 14, and 5, the cumulative frequencies would be 11, 18, 21, 35, and 40, and the cumulative relative frequencies would be 0.275, 0.450, 0.525, 0.875, and 1.000. Construct a table presenting frequencies, relative frequencies, cumulative frequencies, and cumulative relative frequencies, for the data in Exercise 2 of Section 1.3, using the class intervals 14–< 15, 15–< 16,..., 22–< 23.
