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 parameter (symbol and name) controls the center of a normal distribution?
  2. What parameter (symbol and name) controls the dispersion of a normal distribution?
  3. What is the mean and standard deviation of a N(3,2) distribution?
  4. What symbolism is used to represent the variable Q that is normally distributed with a mean of 510 and standard deviation of 70?
  5. Which of these distributions – N(0,1), N(3,2), or N (0,3) – is centered most to the right? Most dispersed? Widest? Tallest?
  6. What does the 68-95-99.7% Rule tell us?
  7. The 68-95-99.7% Rule can only be used for very specific questions. What are those questions?
  8. On a N(10,2), what percent of individuals are between 8 and 12?
  9. On a N(10,2), what percent of individuals are between 4 and 16?
  10. On a N(10,3), what percent of individuals are between 4 and 16?
  11. On a N(10,3), what percent of individuals are greater than 16?
  12. 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.]
  13. What type of question is “What percent of individuals are greater than 16?”?
  14. What type of question is “What is the value such that 20% of individuals are larger?”?
  15. 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).]
