Early Solutions for the 2021 AP Statistics Exam
Math Medic
The College Board typically releases the free response questions for the AP Statistics Exam about 48 hours after the exam. So starting early Wednesday afternoon, we feverishly refreshed the College Board website like we were trying to buy tickets for a Justin Timberlake concert. It turns out that some of our 2021 AP Exam predictions were spot on (part b of the significance test being about Type I, II errors) and totally wrong on others (predicted the wrong significance test).
So here goes with our first attempt at solutions (please be gentle if we have any errors!)
