Answer 1

The correct answer is D. yes because the manager asked everyone who entered the meat aisle.

The store manager is surveying all shoppers in the meat aisle, which allows for a comprehensive view of coupon usage among those entering that specific aisle. This method helps gather relevant data directly from the population being studied (shoppers in the meat aisle). While it's important to acknowledge that this sample may not represent all shoppers in the store, within the context of that specific aisle, it provides useful information.
