We hope your students were good at writing conclusions to a significance test, as this idea showed up in several different ways on the 2023 AP Statistics Exam. As usual, our AP Exam predictions for 2023 had some winners (SOCV, DUFS, purpose of random assignment, interpret slope) and some big losers (wrong significance test!).
So here goes with our first attempt at solutions (please be gentle if we have any errors!)
QUESTION 1: ALASKAN STREAMS
QUESTION 2: FIBER DRIVEWAYS
QUESTION 3: BATH FIZZYS
QUESTION 4: OMEGA-3 SUPPLEMENT
QUESTION 5: TULE ELK
QUESTION 6: CLEO GOLD NECKLACES
