The Mean, Standard Deviation, and Sampling Distribution of the Sample Mean
Read sections 1 and 2 from chapter 6 . Section 1 presents several concrete examples to calculate the exact distributions of the sample mean. Based on these distributions, the corresponding means and standard deviations are computed for demonstrations. Section 2 concerns the sampling distributions of the sample means when the sample size is large. The case when the population is normal is also considered. The central limit theorem is used for large sample approximations. Complete the odd-numbered exercises at the end of each section before checking the answers.
