Chris, Re: the statement " my students will go on to college and read articles from the past, in which these terms are used." I think there are still a lot of people who use the language of type I and type II error in MODERN articles. The issue of accepting a defective lot or rejecting a good lot are both still very actively discussed in the areas of Quality inspection, at least with the folks I know.

Let me offer a couple observations on the Type I/II question. First, I think the thrust of the AP Stat is very much a "p-value" orientation rather than a fixed-level testing orientation. Thus, I would not expect to see the terms Type I and Type II error on the exam. However, the general logic of hypothesis testing is there, and I would certainly want my students to know that decision-making under uncertainty does entail a risk of error. Secondly, my students will go on to college and read articles from the past, in which these terms are used. Thus, I think a consideration of these ideas and terms is necessary irrespective of the AP exam.
