Question D,F, H must be answered

.4 39% 4:28 PM occurrence of rabies in each region (Reference: B. Sayers et al., "A Patterr Analysis Study of a Wildlife Rabies Epizootic," Medical Informatics, Vol. 2, pp. 11-34). The data gives the number of cases of fox rabies found in 16 locations of region I and 15 locations of region II. Region I Data 07 8 7 7 78 0 2 2 2 2 5 0 3 6 Region II Data 2 2 3 2 49 5 4 5 4 2 2 5 6 9 Let /t1, H2 represent the mean number of cases of fox rabies in region I and in region Il respectively. At significance level 0.02, does this information indicate that there is a difference (either way) in the mean number of cases of fox rabies between the two regions? Assume the distribution of rabies cases in both regions is mound-shaned and approximately nor

Explanation / Answer

d)

x1 = 4.125 , x2 = 4.2, s1 = 3.0304 , s2 = 2.336 , n1 = 16 , n2 = 15

t = ( x1 - x2)/sqrt(s1^2/n1 + s2^2/n2)
= (4.125 - 4.2) / sqrt(3.0304^2/16 + 2.326^2/15)
= -0.0776

f)

p value = .9392

h) t value at 81.93% = 1.371

CI = dbar + /- ME

ME = t * sqrt(s1^2/n1 + s2^2/n2)
= 1.371 * sqrt(3.0304^2/16 + 2.326^2/15)
= 1.33

CI = -0.075 +/- ME

= (-1.4004 , 1.2504)
