Sketch a graph of the sampling distribution. Choose the correct graph below.

8.9 -324.1341.9

A normal curve is over a horizontal x overbar axis labeled from negative 324.1 to 341.9 and is centered on 8.9.

111 84.3137.7

A normal curve is over a horizontal x overbar axis labeled from 84.3 to 137.7 and is centered on 111.

8.9 -102.1119.9

A normal curve is over a horizontal x overbar axis labeled from negative 102.1 to 119.9 and is centered on 8.9.

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.
