Answer 1

When the heating and air conditioning firm reviews their last year's sales data for June and August to forecast this year's summer sales, they are using primary data. This is because they are directly analyzing their own past sales figures, which were generated by their business operations.

In contrast, secondary data would involve using information collected from other sources, such as industry reports or studies conducted by other organizations.
