Exam 2 Study Guide: Chapters 11-17

  1. Examine the question for possible bias. If you think the question is biased, indicate how and propose a better question. Look at problems 12.13-15.
  2. Read a report about an experiment. Identify (if possible) the factor(s) in the experiment and the number of levels for each, the number of treatments, the response variable measured, the design (completely, randomized, blocked, or matched), and whether it was blind (or double-blind). Look at problems 13.1-18.
  3. Identify the type of sampling used in each of the situations. Ten parts. Know the sampling methods from chapter 12.
  4. Tell whether or not the probability assignments are plausible. Five parts. Look at problems 14.9-10.
  5. Create a probability distribution from a description and then answer questions based on it. The description will be something like "A six sided die is rolled. The odd numbers are twice as likely to occur as the even numbers." Look at problems 14.11-14.
  6. Use the probability rules to find some probabilities. Look at problems 15.3-6
  7. Find the probabilities of some compound events. Look at problems 14.17-22
  8. Find the mean and standard deviation of a binomial experiment. Look at problems 17.10-14.
  9. Use a joint probability distribution in table form to find some probabilities. Look at problems 15.9-10, 23-24.
  10. Create a tree diagram that illustrates the described situation. Use the tree diagram to complete a table of joint probabilities. Then use the table to answer some probability questions. Look at problems 15.34-36.
  11. Find the expected value and standard deviation for a situation. The probability distribution is given, but you need to know the formulas for finding the mean and standard deviation. Look at problems 16.3-8, 11-14.
  12. Given the means and standard deviations for two independent variables, find the mean, standard deviation, and variance for new variables formed from the old variables. Three parts. Look at problems 16.23-26.
  13. Determine whether or not the described situation satisfies the conditions of a binomial distribution. If they don't, tell why. Five parts. Look at problems 17.1-2.
  14. A table of binomial probabilities from Minitab is given. Use them to find the probabilities asked for. Look at problems 17.9-18.
  15. Perform a simulation using Minitab. Enter the appropriate choices into one column and then use the Calc / Random Data / Sample from Columns command to choose a random sample. Identify whether or not sampling with replacement is required. Describe what you're looking for in Minitab to know whether or not the simulation is a success or what you're looking for in the sample. Record the outcome of each simulation in a table and repeat the simulation 20 times (you can press Control-E and Enter to quickly repeat the simulation). Answer the question based on the results of your simulation. Look at problems 11.9-29.
  16. Similar to question 1.
