To determine how many 8th graders prefer dramas, we need to examine the given data in the table. The table presents the preferences of students from different grade levels for various movie genres.
Here's a detailed breakdown of the data:
| Movie Genre | Superhero | Comedy | Drama | Total |
|-------------------|-----------|--------|-------|-------|
| 6th grade | 12 | 16 | 9 | 37 |
| 7th grade | 15 | 14 | 10 | 39 |
| 8th grade | 17 | 19 | 10 | 46 |
| Total | 44 | 49 | 29 | 122 |
We are specifically interested in the number of 8th graders who prefer dramas. To find this, we locate the cell in the table that corresponds to both the 8th grade row and the Drama column.
From the table:
- In the 8th grade row, under the Drama column, the number given is 10.
Thus, the number of 8th graders who prefer dramas is 10.
