Stats

1. Sets & Probability

   • Sets & Probability
   • De Morgan's Laws
   • Disjoint
     • Can't Occur Simultaneously
   • Conditional
     • A "Given" B etc
     • Bayes Theorem
   • Independence

2. Variables

   • Variables And Distribution
   • Discrete Random
     • Finite Number of Values
     • Distributions
       • Bernoulli[Binomial]...Success/Failure
       • Geometric
       • Poisson
     • Prob. Mass Function
   • Continuous Random
     • Distributions
       • Prob. Density Function
       • Uniform
       • Exponential

3. Normal Distribution

   • N([mew],[sigma]^2)
     • If X~N([mew],[sigma]^2)...Range of X=(Real)
     • P(0.36<Z<1.04)
     • P(Z>P80)=.02...
     • P(X>78)
       • Must Use Equation to Find Z-score: Z=(X-[mew])/[sigma]
   • "Normal" = N(0,1)

4. Models

5. Confidence

   • 2 Controlling Parameters of Normal Distribution: ->Confidence Intervals ->Sample Size
   • Z(alpha) = Critical Value =>Sets the level of Confidence
   • Proportional CI
     • Sample Of Pop instead of Whole Pop
   • Hypothesis Testing
     • Null Hypothesis = Ho
