To create the key for interpreting the stem-and-leaf plot for the given data, follow these steps:
1. Identify the Stems and Leaves:
- The numbers given are in the format of a decimal with two places (e.g., 4.74, 5.09).
- In a stem-and-leaf plot, the stem is typically composed of the integer part of the number.
- The leaf is the decimal part of the number.
2. Define the Stems:
- The stems in this particular case will be the integer parts: 4 and 5.
3. Define the Leaves:
- The leaves will be the decimal portion of the numbers: 74, 64, 60, etc.
4. Create the Key:
- Explain how to interpret the stem and leaf values.
Considering this information, the key for interpreting the stem-and-leaf plot is:
```
Stem: Integer part of number
Leaf: Decimal part of number
```
This key tells us that each value in the plot is split into two components: the stem (the integer part of the weight) and the leaf (the first two digits after the decimal point of the weight). For example, in the number 4.74, "4" is the stem and "74" is the leaf.
