Section by Section List of Test Topics For Exam #2 (Chapters 4-5 from Elementary Statistics, 10th edition, by Triola)

The exam will consist of 20 multiple-choice questions from this list of questions from your homework sections.

 

  1. Determine if a quantity is unusual or usual based on formula m±2s
  2. Classify if a probability as rare or unlikely (the 0.05 rule)
  3. Solve probability problems using the formula card and check answers with calculator
  1. (4-2) Compute probability of an event from empirical data
  2. (4-2) Compute probability of an event from a theoretical description
  3. (4-2) Know that any probability must be between 0 and 1, inclusive
  4. (4-2) Know when a probability is rare or unusual (e.g., less than 5%)
  5. (4-3) Use the Addition Rule in the case of 2 or more compound events
  6. (4-3) Distinguish bet. disjoint (mutually exclusive) or non-disjoint events
  7. (4-4) Use the Multiplication Rule in the case of 2 or more compound events
  8. (4-4) Know when to use the 5% rule to treat 2 or more events as independent (p.163)
  9. (4-5) Know the formula for the probability of an event and its complement
  10. (4-5) Use complementary probability to solve “at least one” problems
  11. (4-5) Use the Conditional Rule in the case of 2 dependent events
  12. (4-7) Be able to compute factorials and combinations (p.185)
  13. (4-7) Know to use combinations when counting unordered outcomes
  14. (5-2) Determine if a table of probabilities represents a probability distribution
  1. (5-2) Classify a random variable as discrete or continuous
  2. (5-2) Compute the mean of a discrete probability distribution
  3. (5-2) Compute the standard deviation of a discrete probability distribution
  4. (5-2) Compute the Expected Value of a probability distribution (e.g., #11, 13, 15 in the homework)
  5. (5-3) Classify a probability problem as binomial or not binomial
  6. (5-3) Compute the binomial probability for a given n, p, and x values
  7. (5-3) Determine the n, p, q, and x values for a given binomial probability problem
  8. (5-3) Compute binomial probability by hand or with a calculator
  9. (5-3) Use the Addition Rule in binomial probability problems
  10. (5-4) Compute the mean of a binomial probability distribution
