Learn about bootstrapping; sampling with replacement; simulating Gaussian mixture, and truncated distribution.
- [Instructor] A year after Mayor Green is elected,…she embarks on a series of very contentious reforms.…There are doubts as to the level of support…that the citizen have in her.…In your job at the newspaper, you're still covering…politics, so you prepare to do another poll.…This time, you ask the people you interview…to give the mayor a grade between zero and ten.…You're feeling lazy, so you take only 100 samples.…Then we import packages, and load the data.…

And, indeed, given the observed histogram it is unlikely…that it has a simple form such as a no amount distribution.…However, we can still use computing by adopting…
