Find the mean and standard deviation of the indicated sampling distribution of sample means. Then sketch a graph of the sampling distribution. the scores on the SAT Italian subject test for the 2018-2020 graduating classes are normally distributed with a mean of 628 and a standard deviation of 110. Random sample of size 25 are drawn from this population and the mean of each sample size is determined.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
