1.1   The data below shows the marks (out of 100), obtained by 16 learners in a Mathematics test
      (Test 1).

          67           77     26         92        48        38         56           58

QUESTION 2

2.1   In a survey, a group of people were asked about the total distance they had travelled from
      their homes in the last week of December 2023. The data collected is represented in the
      frequency table and ogive (cumulative frequency curve) below.

                                 100 km and 300 km.                                                               (2)

      2.1.4                      If all people who travelled more than 350 km were removed from the survey,
                                 how would this affect the median of the data?                                    (1)
