Chapter 7. Understanding Data: Using Statistics for Inference and Estimation Name: Class: Date: From Kiess and Green’s Statistical Concepts for the Behavioral Sciences, 4/e Assignment 7.2 This exercise asks you to compare and contrast the normal distribution with the sampling distribution of the mean. For each statement listed below, write the letter of the statement in the appropriate circle. If a statement applies only to a normal distribution, then write the letter of that statement in the section to the left labeled Normal Distribution . If a statement applies only to a sampling distribution of the mean, then write the letter of that statement in the section to the right labeled Sampling Distribution of the Mean . If a statement applies to both a normal distribution and a sampling distribution of the mean, then write the letter of that statement in the section labeled Both .
