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 irsi gets class lists of all students taking foreign language classes. He then
chooses 10 students from each dimerent language class to survey. Which best explains why the sample he chose may not be
a representative sample?

The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.

Step-by-step explanation:

The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. One class may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample.
