To find out how many students scored 78, we need to count the number of occurrences of the number 78 in the given data. Looking at the key provided, "8[2" represents the number 82. So, we need to count the number of times the number 82 appears in the given data.
To do this, we can go through each row and count the number of times 82 appears. Let's break it down step by step:
1. Start with the first row: 6[8 8 9
- We see that there are no occurrences of 82 in this row.
2. Move to the second row: 7[2 5 5 5 8 8 8 9
- We notice one occurrence of 82 in this row.
3. Proceed to the third row: 8[2 2 2 6 6 9 9
- We observe no occurrences of 82 in this row.
4. Finally, examine the last row: 9[0 0 0 2 2 5 5 5
- We do not find any instances of 82 in this row.
After counting the occurrences of 82 in each row, we determine that there is only one student who scored 78. Therefore, the correct answer is: 1 student.
