Two models predict library circulation from author events. Adult program model: predicted value = 880 + 45(x) and was fit for x-values from 2 to 10. Youth program model: predicted value = 760 + 80(x) and was fit for x-values from 5 to 12. At x = 4, treat a comparison as meaningful only when x is inside both fitted ranges and the gap is at least 100 books. Which statement is best?
