A study of fox rabies in a country gave the followinginformation about different regions and the occurrence of rabies ineach region. A random sample of
n1 = 16
locations in region I gave the following information about thenumber of cases of fox rabies near that location.
x1:
Region I Data
A second random sample of
n2 = 15
locations in region II gave the following information about thenumber of cases of fox rabies near that location.
x2:
Region II Data
(i) Use a calculator with sample mean and sample standarddeviation keys to calculate x1 ands1 in region I, and x2 ands2 in region II. (Round your answers to twodecimal places.)
(ii) Does this information indicate that there is a difference(either way) in the mean number of cases of fox rabies between thetwo regions? Use a 5% level of significance. (Assume thedistribution of rabies cases in both regions is mound-shaped andapproximately normal.)
(a) What is the level of significance?
