Answer :
To find the range of Student 1's results for the distance the iodine diffused into the potato squares, we will follow these steps:
1. List the distances measured by Student 1:
- Trial 1: 3.25 mm
- Trial 2: 3.17 mm
- Trial 3: 3.26 mm
- Trial 4: 3.64 mm
- Trial 5: 3.44 mm
2. Identify the minimum value and the maximum value from Student 1's trials:
- Minimum value: 3.17 mm
- Maximum value: 3.64 mm
3. Calculate the range:
The range is the difference between the maximum and minimum values.
[tex]\[ \text{Range} = \text{Maximum value} - \text{Minimum value} \][/tex]
[tex]\[ \text{Range} = 3.64 \, \text{mm} - 3.17 \, \text{mm} \][/tex]
[tex]\[ \text{Range} = 0.47 \, \text{mm} \][/tex]
Therefore, the range of Student 1's results is [tex]\( 0.47 \)[/tex] mm.
