Self-Assessment Questions


Directions: The following questions are an assessment of your understanding of the material above. If you are not sure of the answers, you may need to rewatch the videos.
Note: These self-assessment questions apply to all the moment videos on this page. 
  1. Define the moment generating function for random variables. Can we have a moment generating function that is undefined at all real numbers?
  2. What is the moment generating function for each of the distributions we have studied?
  3. Why is moment generating function so named? How do you find the third moment of a random variable if you have its moment generating function?
