Question:

As part of a student project, high school students were asked to sprint 50 yards and their times (in seconds) were recorded. A cumulative relative frequency graph of the sprint times is shown here.

100 80 60 40 20 5.8 6.3 6.8 7.3 7.8 8.3 8.8 9.3 9.8 10.3 Sprint time (sec) Cumulative relative frequency (%)
