Answer 2

13.6

Explanation:

To find the mean number of movies that the students saw, we add up all the reported numbers of movies and then divide by the total number of students (which is 8 in this case).

Adding up the reported numbers of movies:

4 + 17 + 17 + 20 + 13 + 4 + 16 + 18 = 109

Dividing by the number of students:

109/8 = 13.625

Rounding to the nearest tenth:

Mean number of movies seen = 13.6

Therefore, the mean number of movies that the students saw, rounded to the nearest tenth, is 13.6.
