Charles wants to find out if the students in foreign language classes spend more time in class speaking in English or in the for
eign 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?
The sample size is not large enough to represent the population.
The sample was not chosen at random.
The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.
The way the sample was chosen does not sample students from each different language class.
C. The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.
The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. Since classes have different numbers of students, one 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 because it doesn't represent the students correctly.
yes he did make it, when he left at 17:00 he had 3:00 hours to make it to the party. if you divide 200/80=2.5 meaning he's able to make it in 2.5 hours.
