WebThis end and this end will be fatter than in a normal distribution. And then we want to find an interval, so if this is a normalized T-distribution the mean is going to be 0. And we want to find interval of T-values between some negative value here and some positive value here that contains 95% of the probability. So this right here has to be 95%. WebDec 14, 2024 · A confidence interval is an estimate of an interval in statistics that may contain a population parameter. The unknown population parameter is found through a …
