Air traffic controllers often experience a high degree of on-the-job stress. In an effort to help air traffic controllers cope with their stress, the impact of a relaxation exercise program was investigated. Thirty air traffic controllers were selected from some of the busiest airports in the country and were administered a scale measuring job-related stress (the scale ranged from 10 to 50, with higher scores indicating greater stress levels). Following the stress scale, the air traffic controllers were trained in a relaxation technique for four weeks and were then administered the job-stress scale a second time. Test statistic used: Dependent Sample t-Test Requirement: State the null and alternative hypothesis.
