Researchers in retail studies wanted to find out how children and adults react to companies’ pricing tactics. They looked at a random sample of 44 10th-grade students, a random sample of pretested adults consisting of 42 people, and a third sample of 71 adults. For each person, they evaluated the response to a pricing tactic. The reported overall level of significance was p < 0.01. A further analysis of differences between every pair of groups was reported as all p > 0.01. Interpret these reported findings. What were the degrees of freedom for Factor, Error, and Total?
