Helicobacter pylori. Twenty mice were infected with H. pylori and then randomly assigned to either cranberry juice treatment (n=10) or treatment with the triple therapy (n=10). After 4 weeks, the researchers examined the mice to determine the frequency of eradication of the H. pylori bacterium. The investigators wished to determine whether there was a significant difference in the eradication of H. pylori between the two treatment groups. Use the SAS output below to answer 

What are the test statistic, degrees of freedom, and p-value for the test you chose (chi-square or Fisher's Exact test)?

Question 19 options:

a) Chi-square = 7.2, d.f. = 1, p = 0.0073

b) Chi-square = 5.0, d.f. = 1, p = 0.0253

c) Fisher's Exact: no test statistic, no d.f., p = 0.023

d) Fisher's Exact: no test statistic, no d.f., p = 0.0115
