1. Stat 321 – Day 14 Continuous Random Variables (Ch. 4)

2. Last Time Famous discrete random variables  Binomial (table), negative binomial/geometric (by hand), hypergeometric (by hand)  Poisson (table)  If use computer on HW, must include output  Be able to identify which have in first bullet

3. Day 13, Example 1: Earthquakes (a) Is Y discrete? (b) Construct histogram 11.522.535 magnitudes # of quakes ?

4. Density Histogram Magnitude above 3 not all that common Area: 2*.04 =.08 => 8% of quakes > 3 Focus on area not just height

5. Using pdf’s

6. Integration! Calculus review:

7. For Tuesday Good idea to bring text to class for Tables Turn in HW 4
