Question
A study of fox rabies in a country gave the following information about different regions and the occurrence of rabies in each region. A random sample of
n1 = 16
locations in region I gave the following information about the number of cases of fox rabies near that location.
x1:
Region I Data
2 | 9 | 9 | 9 | 7 | 8 | 8 | 1 |
3 | 3 | 3 | 2 | 5 | 1 | 4 | 6 |
A second random sample of
n2 = 15
locations in region II gave the following information about the number of cases of fox rabies near that location.
x2:
Region II Data
1 | 1 | 3 | 1 | 4 | 8 | 5 | 4 |
4 | 4 | 2 | 2 | 5 | 6 | 9 |
