WebRead It: Confidence Intervals and the Central Limit Theorem. One application of the central limit theorem is finding confidence intervals. To do this, you need to use the following equation. Note that the z* value is not the same as the z-score described earlier, which was used to standardize the normal distribution. WebThe Central Limit Theorem tells us that the point estimate for the sample mean, x ¯ x ¯, comes from a normal distribution of x ¯ x ¯ 's. This theoretical distribution is called the sampling distribution of x ¯ x ¯ 's. We now investigate the sampling distribution for another important parameter we wish to estimate; p from the binomial probability density function.
