consider the population of all students at your school. A certain portion support mandatory national service following high school. Your friend randomly sampled 20 students from the school, and uses the sample proportion who support MNS to predict the population at the school. You take your own, separate sample of 20 students, and find the sample that supports MNS. a) for the two studies, are the population the same? b) for the two studies, are the sample proportions necessarily the same? explain.
