A library has many identical shelves. All the shelves are full and the numbers of books on each shelf in a certain section are summarised by the following stem-and-leaf diagram.
| 3 | 6 9 9 | (4) |
| 4 | 6 7 | (2) |
| 5 | 0 1 2 2 | (4) |
| 6 | 0 1 1 2 3 4 4 4 5 5 6 6 6 7 8 9 | (20) |
| 7 | 1 1 3 3 3 5 6 7 8 9 9 | (12) |
| 8 | 0 2 4 5 5 6 8 | (7) |
| 9 | 0 1 2 4 4 4 5 5 6 7 7 8 8 9 9 | (18) |
Key: \( 3 \mid 6 \) represents 36 books.
- Find the number of shelves in this section of the library.
- Draw a box-and-whisker plot to represent the data.
In another section all the shelves are full and the numbers of books on each shelf are summarised by the following stem-and-leaf diagram.
| 2 | 1 2 2 3 3 4 5 6 6 6 7 9 | (13) |
| 3 | 0 1 1 2 3 4 5 6 6 7 7 8 8 | (15) |
| 4 | 2 2 3 5 7 8 9 | (8) |
Key: \( 3 \mid 6 \) represents 36 books.
