A city official would like to know if there is public support for increasing funding for arts programs. To collect data, the city official stands outside a concert hall after a show and surveys the first 20 people to exit about their opinion of raising funds for the arts. Which of the following best describes any bias that may arise from the results? Because only the first 20 people were surveyed, the city official may underestimate support for raising funds. Because a convenience sample was taken, the city official should have an unbiased estimate of public support. Because those in the sample generally support the arts, the city official may overestimate support for raising funds. Because those in the sample generally support the arts, the city official should have an unbiased estimate of public support for raising funds.
