Math Test Tomorrow!

First and foremost, I apologize for being out today; I (obviously) did not anticipate being sick and never intended to be out. However, I have the utmost confidence that you can all prepare yourselves to succeed on tomorrow's test. The key to success on tomorrow's test is preparation! Study, study, study! Give me your best effort through this math test and vocab test, and then you'll get a chance to rest!

Here's an outline of what's on the math test tomorrow: (chapters 14-17)
  • Find probability of "at least __ successes" or "at most __ successes" using binomcdf(
  • Find probabilities using "AND" (Remember our first expected value homework? There was a game where you could score 0, 1, or 2 points; the game was played twice and we had to find the probability a person scored a sum of 0, 1, 2, 3, or 4...I would study how we found each of these probabilities).
  • Find an "at least one" probability (either by hand, as in chapter 14, or using binompdf)
  • Find probabilities using a Venn Diagram--you will have to find the value for "the middle," or the overlap--look at your "soccer/basketball" example with a Venn diagram in your notes
  • Find a basic normal model probability (using normalcdf)
  • Find a conditional probability using a two-way (contingency) table
  • Find a conditional probability with a Venn diagram context (look at the owning cats/dogs example on page 1 of our chapter 14/15 mid unit quiz)
  • Find the standard deviation when combining random variables (remember, VARIANCES ALWAYS ADD!)
  • Find basic probabilities using "AND," "OR," and "NOT." (Study the types of problems from your chapter 14 quiz about the spinner, or the roulette example from our chapter 14/15 mid-unit quiz)
  • Find the probability that the first success occurs in the ___th spot (by hand or using geometpdf)
  • Find the probability of an exact number of successes using binompdf
  • Create/use a tree diagram to find "and" probabilities and to find conditional probabilities (study the pregnancy test example from our chapter 14/15 quiz)
  • Find a probability "without replacement"
    • Study the "committee" example from our chapter 14/15 mid-unit quiz
  • Calculate probabilities to complete a probability model
  • Calculate expected value
  • Interpret expected value
And here's what's on the vocab test the following day:
  • 3 questions: identify if two events are disjoint, independent, neither, or both
  • Probability
  • Law of Large Numbers
  • Law of Averages
  • Sample Space
  • Complement
  • Equally Likely
  • Independence
  • Disjoint/Mutually Exclusive
  • Venn Diagram
  • Tree Diagram
  • Conditional Probability
  • Intersection
  • Union
  • Random Variable
  • Probability Model/Probability Distribution
  • Shifting
  • Rescaling
  • Expected Value
  • Standard Deviation/Variance
  • Pythagorean Theorem of Statistics
  • Geometric Probability
  • Binomial Probability
