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

1. 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
2. Lottery
Data is results from playing lottery
Number of failed lottery trials
null model is that the odds are accurate
Statistic is distributed geometrically
3. 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
4. Traffic Lights
Time to failure is the data
Probability of the data under H0
Time to failure is correct
Distribution is also exponential
