- Mondays exercise continued
- Listed in the following order
- Data
- Test Statistic
- Null Model
- Dist. of Test statistic under null model

- Pride of lions:
- The data is the number of males and females in a pride of lions
- Test statistic is the percentage of males in a pride of lions
- The null model is that the percentages are the same
- The dist of the test statistic is binomial

- Lottery
- Data is results from playing lottery
- Number of failed lottery trials
- null model is that the odds are accurate
- Statistic is distributed geometrically

- GPS coordinates
- x,y,z coordinates
- test statistic is the sum of the squared norm of the coordinates minus true coordinates, normalized
- Null model is that these are unbiased
- Test statistic distribution is chi-squared. We are drawing from multiple gaussian distribution and measuring the variance from the known position

- Traffic Lights
- Time to failure is the data
- Probability of the data under H0
- Time to failure is correct
- Distribution is also exponential
