An occupational psychologist is investigating whether there is an association between primary work environment and self-reported burnout level. They collect survey data categorised into four work environments ('Fully Remote', 'Hybrid', 'Open-plan Office', 'Traditional Cubicle') and two levels of burnout ('Moderate/Low', 'Severe').
Using the extract from the table of critical values presented below, determine the critical value for use with the Chi-square (χ2\chi^2χ2) test in this study at the 1% level of significance (p≤0.01p \le 0.01p≤0.01).
