Sampling Distribution Of A Sample Mean, Since our sample size is gr

Sampling Distribution Of A Sample Mean, Since our sample size is greater than or equal to 30, according to the central limit theorem we can assume that the sampling distribution of the sample mean is normal. μx = μ σx = σ/ √n To put it more formally, if you draw random samples of size n, the distribution of the random variable , which consists of sample means, is called the sampling distribution of the sample mean. Explore the concept with various examples. txt) or view presentation slides online. Like the latter, it is symmetric around zero and bell-shaped.
