The best response regarding the validity of the inference made by the store manager is:
No, because the sample is not chosen randomly.
This is because surveying shoppers only in the meat aisle does not represent the entire population of shoppers in the store. It could lead to biased results, as the preferences and behaviors of meat aisle shoppers may not reflect those of all shoppers in the store.
