A research is conducted to examine the mental health status of adults with different education
levels. There are 3 categories of stress levels, namely normal, moderate and severe and 4
education levels, namely secondary, higher secondary, undergraduate and postgraduate levels.
A sample is chosen from the population and the data collected are summarised in the
contingency table below. A x²-test is performed.
