Question

which data collections show bias? check all that apply. ten numbered tickets were selected from a bowl containing all raffle tickets sold. a bank asked its 25 wealthiest customers to complete a satisfaction survey. fifth - graders were asked what desserts should be served with school lunches. every tenth semi - trailer was pulled over and weighed at the state border. college students at the honors library were asked who they voted for in the last election.

Explanation:

1. First option: Sampling only college students at the honors library is a form of selection - bias as it doesn't represent the entire student population.
2. Second option: Selecting every tenth semi - trailer at the state border is systematic sampling and may not be representative if there are patterns related to time, origin etc. of the trailers, showing bias.
3. Third option: Asking only fifth - graders about school lunches is a form of bias as it doesn't account for other grade levels' opinions.
4. Fourth option: Surveying only the 25 wealthiest customers doesn't represent all customers, showing bias.
5. Fifth option: Randomly selecting numbered tickets from a bowl is a random sampling method and generally does not show bias.

Answer:

The first, second, third, and fourth data collections show bias.
