Wildlife: Fox Rabies A study of fox rabies in southern Germany gave the following information about different regions and the occurrence of rabies in each region (Reference: B. Sayers et al., “A Pattern Analysis Study of a Wildlife Rabies Epizootic,”

Medical Informatics, Vol. 2, pp. 11–34). Based on information from this article, a random sample of n1 516 locations in region I gave the following information about the number of cases of fox rabies near that location.

x1: Region I data 1 8 8 8 7 8 8 1 3 3 3 2 5 1 4 6 A second random sample of n2 515 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 (i) Use a calculator with sample mean and sample standard deviation keys to verify that x1 5 4.75 with s1< 2.82 in region I and x2< 3.93 with s2< 2.43 in region II.
(ii) Does this information indicate that there is a difference (either way) in the mean number of cases of fox rabies between the two regions? Use a 5% level of significance. (Assume the distribution of rabies cases in both regions is mound-shaped and approximately normal.)AppendixLO1
