Fishers f test
An F-test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. It is most often used when comparing statistical models that have been fitted to a data set, in order to identify the model that best fits the population from which the data were sampled. Exact "F-tests" … See more Common examples of the use of F-tests include the study of the following cases: • The hypothesis that the means of a given set of normally distributed populations, all having the same standard deviation, are equal. This is … See more • Fox, Karl A. (1980). Intermediate Economic Statistics (Second ed.). New York: John Wiley & Sons. pp. 290–310.

The 95%-CI for the odds ratio spans from 0.000 to 0.6844, thus an odds ratio of 1.0 is far off and you can reject the null hypothesis, that the values in the contingency table are independent. p = 7.9e-12 means 7.9 × 10 − 12, so very close to zero. Conventionally, the test result is considered 'significant' if p < 0.05.
