Document Summary
8. 1 distribution of the sample mean learning objectives: describe the distribution of the sample mean: normal population, describe the distribution of the sample mean: nonnormal population. 8. 1 distribution of the sample mean introduction (1 of 2) 8. 1 distribution of the sample mean introduction (2 of 2) The sampling distribution of a statistic is a probability distribution for all possible values of the statistic computed from a sample of size n. 8. 1 distribution of the sample mean illustrating sampling distributions (1 of 3) Step 1: obtain a simple random sample of size n. 8. 1 distribution of the sample mean illustrating sampling distributions (2 of 3) 8. 1 distribution of the sample mean illustrating sampling distributions (3 of 3) Step 3: assuming that we are sampling from a finite population, repeat steps 1 and 2 until all distinct simple random samples of size n have been obtained. 8. 1. 1 describe the distribution of the sample mean: normal population (1 of 14)
