Explanation:

Step1: Count students per movie count

- For 5 movies: 4 students (dots at 5)
- For 6 movies: 1 student (dot at 6)
- For 7 movies: 3 students (dots at 7)
- For 8 movies: 2 students (dots at 8)
- For 9 movies: 5 students (dots at 9)
- For 10 movies: 3 students (dots at 10)
- For 11 movies: 0 students (no dots at 11)
- For 12 movies: 4 students (dots at 12)
- For 13 movies: 5 students (dots at 13)
- For 14 movies: 3 students (dots at 14)

Step2: Analyze first statement (10 students who watched _ movies)

Sum students: \(4 + 1 + 3 + 2 + 5 + 3 + 0 + 4 + 5 + 3 = 30\) total students.
Check which movie count has 10? Wait, no—wait, maybe sum groups. Wait, maybe the first blank: let's check sums. Wait, maybe the first sentence: "There are 10 students who watched _ movies." Let's sum:
Wait, maybe I misread. Wait, the dot plot: let's recount dots:
5: 4, 6:1, 7:3, 8:2, 9:5, 10:3, 12:4, 13:5, 14:3. Wait, 11:0.
Wait, maybe the first blank: sum of some? Wait, maybe "There are 10 students who watched 9, 13, or 14? No. Wait, maybe the first sentence: let's check total students: \(4 + 1 + 3 + 2 + 5 + 3 + 0 + 4 + 5 + 3 = 30\). Half is 15. Wait, maybe the first blank: let's see, 9 movies: 5, 13:5, 14:3? No. Wait, maybe the first statement: "There are 10 students who watched _ movies." Let's check sum of 9, 13, and 14? 5 + 5 + 3 = 13. No. Wait, 5, 12: 4 + 4 = 8. 9, 12: 5 + 4 = 9. Wait, maybe the first blank is "9, 13" no. Wait, maybe I made a mistake. Wait, the dot plot: let's count again:
5: 4 dots
6: 1 dot
7: 3 dots
8: 2 dots
9: 5 dots
10: 3 dots
11: 0 dots
12: 4 dots
13: 5 dots
14: 3 dots

Total: \(4 + 1 = 5\); \(5 + 3 = 8\); \(8 + 2 = 10\); \(10 + 5 = 15\); \(15 + 3 = 18\); \(18 + 0 = 18\); \(18 + 4 = 22\); \(22 + 5 = 27\); \(27 + 3 = 30\). Correct, 30 students.

First statement: "There are 10 students who watched _ movies." Let's see which group sums to 10? Wait, 5 (4) + 6 (1) + 7 (3) + 8 (2) = 4 + 1 + 3 + 2 = 10. So movies 5–8? Wait, no, the blank is a single number? Wait, maybe the first blank is "9, 13" no. Wait, maybe the first sentence is "There are 10 students who watched 9 movies"? No, 9 has 5. Wait, maybe the problem is about the first drop-down: "There are 10 students who watched [5, 6, 7, 8] movies? Wait, 4 + 1 + 3 + 2 = 10. Yes! So 5,6,7,8 movies: total 4+1+3+2=10. So first blank: 5 to 8? Wait, no, the first sentence: "There are 10 students who watched _ movies." So the answer for first blank is 5 - 8 (sum 10).

Second statement: "There were more students who watched 5 to 7 movies than students who watched _ movies." Students who watched 5–7: 4 + 1 + 3 = 8. Students who watched, say, 10: 3, 11:0, 14:3. Wait, maybe 9: 5. 8 > 5? No, 8 > 3 (10,14) or 0 (11). Wait, maybe the second blank: 9? No, 8 < 5? No. Wait, maybe I messed up. Wait, 5–7: 4+1+3=8. Students who watched 10:3, 11:0, 14:3, 8:2, 6:1. Wait, maybe the second blank is 9? No. Wait, total students: 30. Half is 15. Third statement: "Exactly half the class watched _ movies." Half of 30 is 15. Let's sum from the left: 5(4)+6(1)+7(3)+8(2)+9(5)=4+1+3+2+5=15. So exactly half (15) watched 5–9 movies.

Wait, maybe the first sentence: "There are 10 students who watched 5,6,7,8 movies" (sum 10). Second: "There were more students who watched 5 to 7 (8) than students who watched 10 (3), 11 (0), 14 (3), or 8 (2)? Wait, 8 (5–7) > 5 (9)? No. Wait, maybe the second blank is 9? No. Wait, maybe the third statement: "Exactly half the class watched 5–9 movies" (sum 15, which is half of 30).

So putting it together:
1. There are 10 students who watched 5, 6, 7, or 8 movies (sum 4+1+3+2=10).
2. There were more students who watched 5 to 7 movies (8) than students who watched 10, 11, 14, or 8? Wait, maybe 10: 3, so 8 > 3.
3. Exactly half the class (15) watched 5 to 9 movies (sum 4+1+3+2+5=15).

But since the problem is about selecting from drop-downs, and the dot plot is key, the correct answers (assuming the blanks are for movie ranges or counts) would be:
First blank: 5–8 (sum 10), second blank: 10 (or 11,14), third blank: 5–9.

But since the user's problem is to complete the sentences with the dot plot, the key is to count the dots.

Answer:

(Assuming the drop-down options, but based on analysis:

1. "There are 10 students who watched 5, 6, 7, 8 movies"
2. "There were more students who watched 5 to 7 movies than students who watched 10 (or 11,14) movies"
3. "Exactly half the class watched 5 to 9 movies"

But since the exact options are not given, the process is to count the dots per movie and sum to find the correct groups.)
