Answer:
On average, students in Ms. Vieth’s class read more books during the summer than students in Mr. Chen’s class.
Step-by-step explanation:
If you add all of Mr.Chen's number of books, then divide by the number of students, then do the same for Ms.Vieth, you'd have the average for each. Mr.Chen would have 5%, while Ms.Vieth would have 6.15%.
