WebbThe 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.
