Question: A random sample of size is 30 is selected from a known population with a mean of 10 and a standard deviation of 1.1. Samples

A random sample of size is 30 is selected from a known population with a mean of 10 and a standard deviation of 1.1. Samples of the same size are repeatedly collected, allowing a sampling distribution of sample means to be drawn. What is the approximate standard deviation of the sample means?
