Did you know that people who meet at least three different times within a twenty-four hour period are ninety-eight percent more likely to meet again?

Jennifer E. Smith (1980 - )

In this story from the Journal of Humanistic Mathematics (Volume 7, Issue 1, January 2017), a card shark known as "Lady Jane" attempts to swindle a statistician visiting Las Vegas for a conference. The plot twists and turns as the statistician finally turns the tables on Lady Jane because of her knowledge of the Monty Hall Problem and Bayes' Theorem.

The sample means have a normal distribution
Even if the population does not.
Their center is the center of the population.
When this is true, you can sure do a lot.

Whoa-oh-oh-oh, Central Limit Theorem
For populations with finite variance and mean.
If you know-oh-oh-oh the samples are independent
And distributed identically: that's a stat person's dream.

The further that the population is from normal,
The larger that your sample size must be.
If you're sampling Chicago household incomes,
Sample lots of them to use the CLT!

George Cobb (1947 - 2020)
