To find the range of student 1's results, follow these steps:
1. List the measured distances for student 1. The measurements are:
- 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 maximum value in the list:
- The maximum distance diffused is 3.64 mm.
3. Identify the minimum value in the list:
- The minimum distance diffused is 3.17 mm.
4. Calculate the range by subtracting the minimum value from the maximum value:
[tex]\[
\text{Range} = 3.64 \, \text{mm} - 3.17 \, \text{mm}
\][/tex]
5. Compute the result of the subtraction to find the range:
[tex]\[
\text{Range} = 0.47 \, \text{mm}
\][/tex]
Thus, the range of student 1's results is:
D. 0.47
