    This document summarizes statistical concepts: 1) It provides the mean, variance, and standard deviation for a sample data set of size 5. 2) It discusses the standard error of the mean for a sample and population. The standard error of the mean is shown to be the standard deviation divided by the square root of the sample size. 3) It presents the normal distribution and calculates probabilities based on the normal distribution, such as the probability of an observation falling within a certain number of standard deviations from the mean.
