# Feb 18

The homework for Friday is posted.

Any questions about anything so far, including any of the probability stuff?

## inference

Finish discussing inference, using the sources I listed in Tuesday's notes.

We'll work through an example of hypothesis testing using my coin generators and some python code, perhaps something like this

>>> import urllib.request
>>> url='https://cs.marlboro.college/tools/coins/a.cgi'
>>> b't t h h h h t t t h h h h t t h t t h t t t t t h t t h h h h h h h h t h h t t h h t t h h h t h h h t h h h t h t h t t h h h h h h h t h t t t t t t h h h t t t t h h t h h t t t t h h h t h t h h\\n'


... and maybe this

>>> from scratch.statistics import mean, standard_deviation
>>> simulations = [sum(randint(0,1) for i in range(100)) for _ in range(count)]
>>> print(mean(simulations))
>>> print(standard_deviation(simulations))


... and some thinking about normal distributions and probabilities.

Are these fair coin flips? Let's design and work through a hypothesis test or two in class.

I've uploaded the jupyter notebook that we did in class.
