My second day of classes went really well and then the unexpected happened. Two unexpected things, actually. First, we did a simulation in Probability and Statistics. The scenario: an airline company needs to select 8 pilots at random from a group of 15 male and 10 female pilots. The results obtained by the airline were 5 females and 3 males. But wait, shouldn't we have more males than females? That is what one might think based on the ratio of the original group. Is it likely to get these results (5 females and 3 males) by chance alone? We used playing cards to simulate the results and the dotplot here shows our collective results.
So, what was the second unexpected thing? If you read the title to this blog, you guessed it. Two minutes after the school day ended, I slipped in some water that someone had spilled in the hall. I came crashing down on my right knee in the process. At this moment, my knee hurts to bend it and it is being iced. A special thanks to my advisees in the hallway, Annie and Elliot, for making sure I was ok.
