        In order to organize this data, complete the following frequency distribution
        and construct a histogram for this data:

                    Kilometres                Frequency                  Relative
                                                                        Frequency
                        1–3
                        4–6
                        7–9
                      10 – 12
                      13 – 15

                       Total


     2. Twenty five applicants to the Canadian Army are given a blood test to
        determine their blood type. The data set is:

        A      B        B        AB   O
        O      O        B        AB   B

        AB     A        O        B    A

        Complete the following frequency distribution and construct a bar chart for this
        data.
