Business Analyst: National Motors began selling the Luxora-its new model of sedan-in June. Last week, National released sales figures for the summer months of June, July, and August that showed that by the end of August only 80,000 Luxoras had been sold. Therefore, National will probably not meet its target of selling 500,000 Luxoras in the model's first twelve months.

Which of the following would be most useful to establish in order to evaluate the analyst's prediction?

【选项】Whether new-car sales are typically lower in the summer months than at any other time of the year
