\#7-8: Identify why the following survey plans involve bias. 7) An amusement park manager wants to know which roller coaster customers Bke best. He goes to their newest rollercoaster, the Grand Canyon Coaster, and asks every \( 5^{\text {th }} \) person waing in line for that ride. 8) To determine which candidate is more Bkely to win an election, a person asks people, "Are - you going to vote for the experienced incumbent Tarita Fowkes or the young, precocious Derek Ames?"

The amusement park manager's survey is biased because he's only polling customers in line for the Grand Canyon Coaster, which may not accurately represent the preferences of all visitors. Those waiting to ride this specific coaster might have a preference for thrill rides, skewing the results and ignoring those who favor gentler attractions or have yet to try the Grand Canyon Coaster. Similarly, the election survey is biased due to its leading question. By framing it in a way that emphasizes "experienced incumbent" versus "young, precocious," it may sway responses in favor of one candidate while alienating the other. This wording presupposes positive attributes for the incumbent and casts a less favorable light on the challenger, which can distort public opinion and the accuracy of the survey results.
