Final answer:
The psychological variable affecting Mei's purchase of the Sharpen X Pro tablet is her attitude, which incorporates her feelings, expected behavior, and beliefs about the product. The correct answer of the question is attitude.
Step-by-step explanation:
The psychological variable in play as Mei makes her decision to buy the Sharpen X Pro tablet is her attitude. An attitude encompasses our evaluations and can be favorable or unfavorable towards various aspects such as products, ideas, or objects.
It includes three components: an affective component (feelings), a behavioral component (how our attitudes influence our actions), and a cognitive component (beliefs and knowledge).
Mei's decision process reflects these components as she considers the tablet's ease of use (affective), how it will fit into her life by communicating with other devices (behavioral), and assesses its value based on price (cognitive). The combination of positive feelings, expected behaviors, and beliefs ultimately shapes Mei's attitude towards the product and influences her purchase decision.
