Alocal tv station conducted a "pulse-poll" about the upcoming mayoral election. evening news viewers were invited to text in their votes, with the results being announced on the late-night news. based on the texts, the station predicted that the current mayor would win the election with 52% of the vote. they were wrong and the mayor lost, getting only 46% of the vote. do you think the station's faulty prediction is more likely to be a result of bias or sampling error? explain.
