Asnack manufacturer realizes that he must increase the salt content of his company's chips by at least 3% in order for a sample of consumers to notice that the chips are saltier than they were before. this example most nearly illustrates the concept of a(n): multiple choice absolute threshold. difference threshold. frequency threshold.
