In a Number of Universities in Australia, Lecture Recordings Online

question 37

Essay

In a number of universities in Australia, lecture recordings online are provided to all students. There is
growing concern amongst teaching staff that lecture recordings are used as a substitute for lecture
attendance and that this is leading to a greater fail rate.
At one particular university, a random sample of 224 students is taken, where the students are asked if
they attended the majority of lectures for the last exam they took, or if they viewed the majority of
lecture recordings online and then the student's records are followed up to see if the student passed
that course. $$\begin{array} { | c | c | c | } \hline & \text { Attended lectures } & \text { Viewed lecture recordings online } \\\hline \text { Fail } & 40 & 80 \\\hline \text { Pass } & 56 & 48 \\\hline\end{array}$$ Conduct a test to determine if enough evidence exists to infer that lecture attendance and passing a
university course are related. Test at the 10% level of significance.
