Two students performed the same experiment, testing how far iodine will diffuse through starchy tissue, such as potatoes. They cut 5 potato squares each, all of equal sizes, and placed them into small cups with iodine solution for 15 minutes. Then they measured how far from the edge of the potato the iodine diffused into the potatoes, in millimeters.

\begin{array}{l|c|c|c|c|c|}
& \text{Distance Diffused (mm)} \\
\hline
\text{Student 1} & 3.25 & 3.17 & 3.26 & 3.64 & 3.44 \\
\text{Student 2} & 3.14 & 3.43 & 3.22 & 3.37 & 3.28 \\
\end{array}

What is the range of Student 1's results?



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.
