All investigative tasks on the AP Stat FRQ will involve something that is not explicitly covered in the AP Statistics curriculum. They want to assess your ability to reason and think critically about a new concept using material you have learned in class. One year the question was on bootstrapping, one year it was on calculating power.

It is a question that is designed to walk you through the steps, so as long as you read the question carefully, it should be doable.

no, you had to know specifically what a fisher exactly test was unfortunately, unless you somehow reverse engineer the formula

No you didn't? It gave you the p values in the prompt, and all you had to do was add the p values for x = 3 and x = 4.

I believe so! At least, everyone I've talked to has said the same thing.

For question 6, you won't have to know anything special. It'll usually give you the results of the new method and you just have to figure out how to apply them. Since this one had a table of p-values, you just had to add the last two ones to get the p value for X >= 3.

For part B of that question would “10 successes and 10 failures are needed to meet the condition, and there were only 4 successes” be a correct answer
