Probability Rules
Practice: Look over and understand the probabilities
lab. Questions will be mostly extremely similar to the labs
- Notation P()
- Disjoint events
- Conditional Probabilities
- How to check for Independence
- Algebra
- Complement
- Additive Rule
- Multiplicative Rule
- BIG: Get probabilities from Tables
- Calculate Odds
- Odds-Ratio
- calculate
- Interpret
- association?
Confidence Intervals
Practice: Look over the CI labs and understand the
solutions. Questions will mostly be extremely similar to
labs
Practice: Go through the CI quick-guides and know
how to use formulas, use correct t or z values, and check conditions
- Sampling Distributions
- Standard Error
- Margin of Error
- 68-95-99.7% Rule
- Central Limit Theorem (CLT)
- Goal for CIs
- HUGE: define/describe parameters and statistics in
context
- ‘confidence’ meaning
- Make CI’s for the 4 scenarios (formulas will be given)
- Check conditions
- Know which z* or t* value to use in CI
- Interpret CIs
- Check if certain values are plausible
- When and why do we use t-distribution instead of Normal
