Research has indicated that the stress produced by today's lifestyles results in health problems for a large proportion of society. An article in the International Journal of Sports Psychology (July-Sept. 1990) evaluated the relationship between physical fitness and stress.

Five hundred forty-nine employees of companies that participate in the Health Examination Program offered Services (HAS) were classifitness levels: good, average,

and poor. Each person was tested for signs of stress. The table reports the results for the three groups. [Note: The proportions given are the proportions of the entire group that show signs of stress and fall into each particular fitness level.] Do the data provide evidence to indicate that the likelihood for stress is dependent on an employee's fitness level?
