Answer 1

Here is a back-to-back stem-and-leaf diagram comparing the number of visitors per day at Shop A and Shop B:

```

Shop A:

Stem | Leaf

-----|------

0 | 5

2 | 2 2 2 3 8

4 | 9

5 | 8

Shop B:

Stem | Leaf

-----|------

0 | 5 5 6 7

2 | 3 6

5 | 5

Key:

7 represents 76 people

```

To compare the number of people visiting Shop A and Shop B, we can observe that Shop A generally has higher visitor counts compared to Shop B. Shop A has visitors ranging from 58 to 96, while Shop B has visitors ranging from 55 to 76. However, it is important to note that the stem-and-leaf diagram only provides a visual representation of the data, and further analysis may be required to draw more precise conclusions.
