Leo wants to determine the average number of texts middle school students send in a day. Since all middle school
students are enrolled in history, he randamly surveyed 4 'students from each of Mr. Barnes's eighth-grade history
classes. Ms. Lopez and Mrs. Frank also teach eighth-grade history. What should Leo do to ensure his sample is
representative of all middle school students?
O He should take the sample as is because he randomly surveyed students in each of Mr. Barnes's classes.
He should also take a sample from Ms. Lopez's and Mrs. Frank's classes so that each student has the same
chance of being chosen.
O He should also take a sample from each of the other history classes in all of the other grades in the middle school.
O He should survey al the students in all the history classes to make sure he collects enough data.
