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.

B) A bank asked its 25 wealthiest customers to complete a satisfaction survey

C) Fifth graders were asked what desserts should be served with school lunches.

E) College students at the honors library were asked who they voted for in the last election.

Step-by-step explanation:

All of these example are where one specific group is chosen to represent the whole population.

The 25 wealthiest members of the bank are going to be happier with the bank than the population

Fifth graders will have different opinions about dessert choices than the rest of the school

College students in a certain place might be gathering because of their political views. You never know.

In order to be free of bias, a sample must be taken RANDOMLY, with all members of the population having an equal chance of being selected
