A case-control study of foodborne acute gastroenteritis was
conducted during an outbreak. Eating raw seafood was investigated
as an exposure. There were 165 cases. The odds ratio was 2.0,
the 95% confidence interval was 0.9 to 6.0 and the p-value
was 0.2. The significance level for the study was 0.05.

2) Is the odds ratio statistically significant (different than
1.0)? Explain why you think that the odds ratio is or is not
statistically significant.
