The 99% confidence interval is larger than the 95% confidence interval, and thus is more likely. to include the true mean. Î± = the probability a confidence interval will not include the population parameter, 1 - Î± = the. probability the population parameter will be in the interval. The 100(1 - Î±)% confidence interval. will include the true value of the population parameter with probability 1 - Î±, i.e., if Î± = .05, the. probability is about .95 that the 95% confidence interval will include the true population. parameter.
