- The text presents three statistical reasoning problems with increasing difficulty.
- Problem 1 involves sorting fractions (successes/trials) while accounting for uncertainty to avoid over-estimation, using binomial distribution models.
- Problem 2 focuses on identifying unexpected domestic burglaries by modeling counts with Poisson or continuous distributions based on factors like property crimes and income.
- Problem 3 estimates the number of distinct buses passing a stop using multinomial distribution and likelihood profiles, given sighting data over two weeks.
- Solutions include Bayesian and likelihoodist approaches, with R code examples for practical implementation.
- The author invites feedback for errors or alternative solutions via email.
