many large cities have considered or passed proposals that ban the use of plastic grocery bags in stores. a concerned student would like to measure if residents of her hometown would consider a similar ban on plastic bags. standing in a busy shopping area, the student approaches adults and asks, items made of plastics are a dangerous, growing source of pollution to our worlds oceans and threaten many animal species. given this, would you support a ban on plastic shopping bags in our city stores? how might the results of this survey be biased in estimating the proportion of all town residents who would support a ban on plastic bags? the student may overestimate support for a plastic bag ban because only adults in the shopping area were chosen to participate. the student may overestimate support for a plastic bag ban because the wording of the question may influence adults to support a ban. the student may underestimate support for a plastic bag ban because the wording of the question may influence adults to not support a ban. the student may underestimate support for a plastic bag ban because some adults may not want to answer questions about the environment.
