Four students did a survey to find the soda flavor sixth-grade students prefer. The table below shows the method each student used to conduct the survey: Student Method Trey Asked 100 students at random from his seventh-grade class what their favorite soda flavor is Jesse Asked 100 sixth-grade students at random what their favorite soda flavor is Nita Asked 100 eighth-grade students at random what their favorite soda flavor is Ruben Asked 100 third-grade students at random what their favorite soda flavor is Which student's survey not biased?
Jesse is the only one who surveyed sixth grades, which is what the point of the survey was. They are all biased because they each asked a certain grade. But in the case of this problem, Jesse is the most probable answer.
