1. Market researchers carried out an analysis of the emotions that arise in cus- tomers who buy or do not buy a product at an unintended purchase opportunity and how these emotions later affect the subjects' responses to advertisements by the makers of the product they bought or declined to buy. The results were analyzed using a mixed design and blocking, and the reported results were as follows.14
Main effects: F (1, 233) = 26.04
Interactions: F (1, 233) = 14.05
Interpret these ?ndings.
