TESTS!

Tomorrow we have our probability test (chapters 14-17)! Here's a list of what's covered:

  • Binomial Probability: (chapter 17)
    • At least, at most, and between questions (binomcdf)
    • "Exactly" questions (binompdf)
    • Find expected value, standard deviation for a binomial model
  • Find probability of "at least one" (chapter 14 and chapter 17)
  • Calculating probabilities for events that overlap: Venn diagrams (ch. 15)
  • Calculating conditional probabilities (ch. 15)
    • With tree diagrams
    • With contingency or two way tables
    • Given a table or given probabilities
  • Calculating probabilities with the Normal model (ch. 6/ch. 16)
  • Finding new expected value, standard deviation, variance, when combining random variables (ch. 16)
    • Pythagorean Thm. of Statistics
  • Calculating "basic" probabilities using words, and, or (ch. 14)--like our spinner or blood type ch. 14 quiz
  • Geometric probabilities (ch. 14/ch. 17)
    • Find probability that the first success it the ___th spot
  • Calculating probabilities without replacement (ch. 15)
  • Using tree diagrams to model scenarios and calculate probabilities (ch. 15)
  • Expected value and standard deviation of a probability model (ch. 16)
    • Create probability model
    • Find expected value (show work)
    • Find standard deviation (on calc)
    • Use expected value to make decisions
