6. Last week Jerry surveyed customers leaving Tony's Tropical Fish store. Of the 75 people surveyed, 68 said fish were their favorite pet. Based on these results Jerry concluded that fish was the favorite pet among all the people in his town. Which is the best explanation for why his conclusion might not be valid?

Jerry's conclusion might not be valid because the sample he surveyed is not representative of the entire population of the town. By only surveying customers leaving a pet store, he is likely to have sampled individuals who already have a preference for fish, skewing the results. A broader survey including people with varying pet preferences would provide a more accurate picture of the town's favorite pet. Additionally, confirmation bias could play a role in Jerry’s reasoning. Since he was surveying customers at a fish store, he may unconsciously focus on confirming his hypothesis that fish are the most popular pets, overlooking perspectives from non-fish owners or those who don’t have pets. A more objective approach would yield more reliable insights.
