Confidence intervals we have covered, although I'm sure there is plenty more of it. I'm not sure if we covered the odds ratio. I don't remember and don't see that in the part of the book we covered (another course which is the continuation uses the same book and all so we may learn more of it in there). But that course is offered in the normal course time.
