6 2 9
7 6 9
8 1 2 6 6
9 6
To determine the number of students represented by the stem-and-leaf plot, you need to count the individual leaves and add them up.
Looking at the plot, let's go stem by stem:
- For the stem "5", we have 4 leaves: 0, 3, 6, and 9.
- For the stem "6", we have 2 leaves: 2 and 9.
- For the stem "7", we have 2 leaves: 6 and 9.
- For the stem "8", we have 4 leaves: 1, 2, 6, and 6.
- For the stem "9", we have 1 leaf: 6.
Counting the leaves from each stem, we have a total of 4 + 2 + 2 + 4 + 1 = 13 leaves.
Therefore, the stem-and-leaf plot represents 13 students.
