Scott wants to know if there is a relationship between attendance
at a particular class and whether students pass or fail the final
exam. He notes whether each of his 30 students were present or
absent at the particular class of interest, and finds that 21 of
the students were present. He then also notes whether each student
passes or fails the final exam. Of the 21 students who were present
at the class of interest, 18 of them passed the final exam. Of the
9 students who were not present, all of them passed the final exam.
Is there a significant relationship between attendance at a
particular class and whether students pass or fail the final
exam?
