Question relate to a study by van der Colff and Rothmann (2009) who assessed whether or not occupational stress, sense of coherence and coping strategies predict burnout and the work engagement of registered nurses. The table below shows a multiple regression analysis with emotional exhaustion as the criterion variable and three types of stress as the explanatory (predictor variables).

12. Emotional exhaustion is predicted by the following regression equation:

a) y = (0.060 × lack of organisational support) + (0.120 × stress job demands) − (.03 × nursing-specific demands) + 7.110

b) y = (0.19 × lack of organisational support) + (0.120 × stress job demands) − (.03 × nursing-specific demands) + 7.110

c) y = (0.60 × lack of organisational support) + (0.120 × stress job demands) − (.03 × nursing-specific demands) − 7.110

d) y = (0.19 × lack of organisational support) + (0.120 × stress job demands) − (.03 × nursing-specific demands) + 7.110
