Final answer:
The manufacturer is interested in the effect of celebrity endorsements on purchases, how gender may influence this, and any interaction effects between celebrity endorsements and gender.
Step-by-step explanation:
The clothing manufacturer is interested in analyzing the influence of celebrity endorsements on purchasing decisions. Specifically, they're investigating whether the presence of celebrities in commercials affects consumer behavior, and if this is further influenced by the gender of the potential buyer. When assessing the impact on purchasing decisions, there are several factors to consider: the celebrity's credibility and attractiveness (which can make them more persuasive), the nature and intensity of the persuasion, and ethical considerations such as the disclosure of paid relationships. Additionally, the manufacturer aims to evaluate if there's an interaction effect where the influence of celebrity endorsements might vary between different genders, adding a layer of complexity to their analysis. Results from such studies are crucial as brand ambassadorships and celebrity influence are significant in shaping consumer preferences, affects demand, and ultimately drive sales.
