This is my take on the ubiquitous M&Ms counting activity. Each student records the color proportions in a fun-size bag of M&Ms. We pool the class data and run a Chi-Square goodness-of-fit test to determine whether or not the color proportions match those claimed on the manufacturer's website. We consistently find that the proportions do not match. The blue M&Ms, in particular, are underrepresented. This activity also includes a review of the 1-proportion z confidence interval.

A cartoon to teach about the interpretation of confidence statements. The cartoon plays on the idea of what would happen if the same process was repeated over-and-over again.

A cartoon to teach the idea that patterns will appear in data if you observe enough data at random. The cartoon plays on the famous "million monkeys typing Shakespeare" problem. Extensions of that problem have many applications. For example, allowing for random letters to be randomly changed and then fixed when they agree with the desired text have applications to modeling molecular evolution.
