Answer 1

The correct response is:

No, because the sample is not chosen randomly.

While the manager surveyed everyone who entered the meat aisle, this method introduces bias as it only captures a subset of shoppers (those who are currently in the meat aisle) and does not account for the behavior of shoppers in other aisles or those who do not enter the store at all. Therefore, the results cannot be generalized to all shoppers accurately.
