Under the null hypothesis, the probability of observing 4 or more successes (people with greater savings than charges) out of 6 trials is calculated as: P(X >= 4) = 1 - P(X <= 3)

WebTo hypothesis test with the binomial distribution, we must calculate the probability, p p, of the observed event and any more extreme event happening. We compare this to the level of significance α α. If p > α p > α then we do not reject the null hypothesis. If p < α p < α we accept the alternative hypothesis. Worked Example Worked Example 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.
