An airport manager is interested in relationship between job satisfaction and stress. In his own airport, the manager asked the random sample of workers two questions. The first question asked how satisfied workers were with their job and had them rate their satisfaction on the scale from 1 to 50. The second question asked how stressful they found their job in the given week. Again the workers rated their stress level on scale from 1 to 50.
