Final answer:
The question lacks the necessary details to address the specifics about DVD rentals. However, for the scenario given, the best response is to explain the return policy, which is most direct and helpful for the customer's inquiry.
Step-by-step explanation:
The question seems to be incomplete and lacks the necessary information to provide a solution for parts e and f of a given problem. Additionally, the context of the original problem that would provide details on 'Video to Go' and its comparison to another store or metrics about DVD rentals per customer is missing. Without this context, calculating the expected number of DVDs rented per customer or for 300 customers is not possible. Therefore, the only part of the question I can address accurately is the scenario involving the sales associate and the customer inquiring about the return policy.
In the scenario of the sales associate and the customer, the best response would be option D: Explain the return policy, and the customer may have. This option provides direct, helpful information that the customer has requested and demonstrates good customer service. Inquiring about whether the customer is looking for a better deal, about the timing of their trip, or expressing a vested interest in commission-based follow-ups could be perceived as less professional or may not address the customer's concerns adequately.
