Hello SBI listserv participants and SBI blog readers,
Hope you are enjoying your Saturday morning!
First, Thank you for your discussions on/contributions to the listserv - it is great to hear about all the things that statistics teachers are doing in their classes!
Second, we have several new articles on the Simulation-based Inference blog (https://www.causeweb.org/sbi/) that have been recently posted:
1) We have two new posts on "How to use real data" by Kevin Ross and Nathan Tintle.
2) Erin Blankenship, Karen McGaughey, and Kathryn Dobeck have written about their experiences and what they thought was "The hardest thing about getting started with simulation-based curricula."
3) For readers interested in "How to implement simulation-based methods in high school classrooms/AP Statistics classes" - we have articles from Bob Peterson, Catherine Case, and Josh Tabor, all AP Statistics teachers, writing about their experiences.
On behalf of the ISI team, I'd like to thank all our blog contributors for writing these pieces for us.
I hope you enjoy reading these articles, and others posted on the blog, as much as I do!
Have a nice weekend!

Happy summer everyone,
I thought I would send out a message I received yesterday. A local
journalist reached out to me (I taught his daughters) with the following
question, and I thought it was a nice problem to send out to everyone.
Even though our school year is over, I've sent it along to my students to
see if anyone is interested to try and answer this question for him, or
even to possibly present to the local town council.
Enjoy!
In 2007, Ross Valley residents voted on a flood tax. You had to sign the
ballot (which was unusual) and 21% of the ballots were not signed and
thrown out. The "valid" votes were split essentially 50-50 (50.1% "no" vs.
49.9% "yes") but the 1,672 tossed out votes were 56.33% "no" and 43.67%
"yes." Assuming there is no reason why the unsigned ballots would be more
likely "yes" or "no, " can you calculate the odds of this 56.33-43.67 split
for a 50-50 event? Many of us suspect foul play, and the matter is of
urgency now as the tax money is about to be used to tear up San Anselmo's
Memorial Park. Your names will NOT be used; it's purely my mathematical
curiosity. Thanks. -- Barry
