Charles wants to find out if the students in foreign language classes spend more time in class speaking in English or in the
foreign language they are studying. Charles first gets class lists of all students taking foreign language classes. He then
chooses 10 students from each different language class to survey. Which best explains why the sample he chose may not be
a representative sample?
