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.
Answer
Brief Explanations:
Bias occurs when a sample is not representative of the population. Selecting only the wealthiest customers, asking only fifth - graders about school lunch desserts, and asking only college students at the honors library about voting are non - representative samples. Selecting numbered tickets from a bowl and weighing every tenth semi - trailer are more likely to be random and representative.
