Answer:
Both samples exhibit the same variability.
Step-by-step explanation:
The two samples are:
Sample 1: 13, 10, 9, 7, 9, 6, 13, 6
Sample 2: 13, 6, 13, 6, 9, 13, 9, 6
Th formula to compute the range is:
![Range=Maximum-Minimum](https://tex.z-dn.net/?f=Range%3DMaximum-Minimum)
- The sample range of sample 1 is:
Maximum = 13
Minimum = 6
![Range_{1}=Maximum-Minimum\\=13-6\\=7](https://tex.z-dn.net/?f=Range_%7B1%7D%3DMaximum-Minimum%5C%5C%3D13-6%5C%5C%3D7)
- The sample range of sample 2 is:
Maximum = 13
Minimum = 6
![Range_{2}=Maximum-Minimum\\=13-6\\=7](https://tex.z-dn.net/?f=Range_%7B2%7D%3DMaximum-Minimum%5C%5C%3D13-6%5C%5C%3D7)
The range of both the sample is same.
Thus, both samples exhibit the same variability.
