For the first time in the history of the AP Statistics exam, there was not a free response question asking students to perform a full significance test! Our students were so disappointed. But this move by the College Board did open up room for some really great questions for this year's exam.
As usual, our AP Exam predictions for 2022 had some winners (describe a scatterplot, interpret slope, 1-proportion z-interval, matched-pairs) and some losers (no significance test, way off on the investigative task).
So here goes with our first attempt at solutions (please be gentle if we have any errors!)
QUESTION 1: BULLFROGS
QUESTION 2: ACNE TREATMENT
QUESTION 3: SHAMPOO BOTTLES
QUESTION 4: TEENAGERS VIDEO STREAMING
QUESTION 5: DARK VS. WHITE CHOCOLATE
QUESTION 6: ALLERGY CLINICS
