Web2 apr. 2015 · For a specific confidence interval from one study, the interval either contains the population value or it does not—there’s no room for probabilities other than 0 or 1. And you can't choose between these two possibilities because you don’t know the value of the population parameter. WebOur null hypothesis is that the true difference in proportions is zero. So 95% of the time that we do this, if we assume that the null hypothesis is true, we will overlap with zero. Or another way you can think about it. 5% of confidence intervals would not overlap with zero.
