*"It was pretty easy"*

This seems to be the overwhelming response from AP Stats students around the country when asked about the 2024 exam. Even when asked about the Investigative Task, most students felt pretty good about it. Let's hope that this confidence translates into amazing AP scores for the year.

As far as predictions, we are so proud of O HOLISTIC ONE for correctly predicting the **two-proportion z-test**! While this prediction was a big win, there were definitely others that fell short.Â

As is tradition now, here is our first attempt at solutions. Please be gentle if we made any mistakes!

wait for the standard deviation problem for a geometric distribution i plugged in the same values, I even wrote the formula on my paper and ended up getting an answer of 3. something, not 11.9 do you think ill at least get a P or an I on that part

I put a T-test and I put my null for part a. Am I getting an "I" for that section?

Any thoughts as to why my students had a different version of the test than this?

In 6a, I said "T Test" instead of "T Interval", ugh...I think I did everything else right

AP Stats Teacher here. Parts of this Exam I like (FRQ 1, two-sample z test; FRQ 5 multi-unit with probability leading into chi-square test for independence; the Investigative Task focused on a new measure of skew, though I though it was a bit too easy) but parts of it I really do not like, especially the probability question FRQ 3. To have all of part (a) resting on pulling formulas for Mean and SD of a geometric distribution from the Formula Sheet seems weak to me. The question does improve from there, with a more open-ended exploration of Conradâ€™s probability. But Normal probability and binomial probability are so much more central to our course, and this question seemed way offâ€¦
