Binomial Example

Also Gamma and Poisson

For Normal, can change both variables. Only was able to change on above examples.

Central Limit Theorem. If you take enough samples (as n goes to infinity), you can treat things as normal.

10 if variables are close to normal 30 (t-distribution starts to look like normal about 30) 50 . ..

Slide 56, Gamma example (sums of previously)

8|alpha is 8 given alpha.

Gamma distribution in EXCEL is different than notes in Microsoft. Need to invert B. Different forms of function.
