### Week 5 survey results: number of heads (binomial distribution)

I've made a movie out of the coin-flip results. Each frame of the movie adds a single coin-flip.

I plotted 2 histograms: the top one shows the total number of each result, and the bottom shows the proportion or density of each result. You can see the Y-axis of the top histogram change as we add flips.

What would this movie look like if we added another 1,000 flips?

### Lab 2

The Lab 2 answer key is available here.

A lab rewrite can earn you up to 50% of missed points. Rewrite questions are marked with @@.

Identify errors/typos in the key for extra credit. See answer key for details.

Note that Lab 2 is worth 95 points (it says 100 on the assignment - typo), with a possible 5 points of extra credit.
