Sampling Distributions for Differences in Sample Means

This study guide covers sampling distributions of the difference between two means. It explains key formulas for the mean and standard deviation of this distribution. The guide emphasizes the Central Limit Theorem (CLT) and its application to these distributions, including the condition of large sample sizes (n ≥ 30). Finally, it provides a practice problem and further practice questions with solutions, focusing on formula application, CLT conditions, and interpretation of results.
