The track-and-field coach wants to know whether the students in the entire school prefer track races or field events. The coach draws a random sample from the following groups: All students in each grade All teachers in the school All boys in each grade in the school All students on the track-and-field team Which group best represents the population she should take a random sample from to get the best results for her survey? All students in each grade All teachers in the school All boys in each grade in the school All students on the track-and-field team
