WebBinomial test. If we have two possible categories (e.g., “pass”/“fail,” “female”/“male,” etc.), we can use the Binomial test to see if their proportions deviate from some null hypothesis proportion. We talked about this via problem via sampling, but that served to explain the logic, rather than provide practical advice.
