When demand for a factory's products is high, more money is spent at the factory for safety precautions and machinery maintenance than demand is low. Thus the average number of on-the-job accidents per employee each month should be bower during periods when demand is high than when demand is low and less money is available for safety precautions and machinery maintenance. Which of the following,if true about a factory when demand for its product is high casts the most serious doubt on the conclusion drawn above?
