Use the preparation materials to prepare hand-written answers for the following questions. Please ask any questions on the "Questions -- Preparation Guide" on the course Team (see link on the homepage.)
  1. What is the difference between a “Forward” and a “Reverse” normal distribution question? [Hint: what is given and what is asked for in each type of question.]
  2. What function in R is used to compute the area under the normal distribution curve?
  3. This function requires three arguments.
    1. What is given for the first argument for a “Forward” question?
    2. What is given for the first argument for a “Reverse” question? What must you make sure of in this situation?
    3. What are the other two required arguments?
  4. This R function defaults to compute areas in a certain direction.
    1. What is that direction?
    2. What argument is used to make this function compute areas in the other direction?
  5. This R function also defaults to a specific type of normal distribution calculation.
    1. What is that type of question?
    2. What argument is used to make this function compute the other type of normal distribution question?
  6. What does a Z-score (or standardized value) measure?
  7. How is a Z-score (or standardized) value calculated?
  8. What questions do you have from this reading that you would like me to address? [Please be as specific as possible. Don’t just say “everything” or “I don’t understand anything.” Of course, you can ask questions about the reading before class on MS Teams (see link above).]
