Statistics question

Can anyone explain to me why the t-statistic approaches the z-score as n approaches infinity, rather than as n approaches N? Is it just assumed that an unknown population size is infinite? I asked the teacher, and she didn't know. It's not important to actual calculations, of course, because there's obviously no way for n to be greater than N; I'm just curious.

Life is lifey

I just picked up my mail, and it consisted of a bank statement, a check, a medical bill (more than $200, ouch), and a letter about a loan. This is the kind of stuff people warned me about when I was a kid and said I wanted to grow up. Bills and taxes and responsibility are no fun, they said. Well, y'know what? It's totally worth it. So far, the positives of adulthood far outweigh the negatives.

I've been dwelling on a flaw of mine, and then realized that several of the people I admire most share that flaw. So I feel a little better about that. Mom always says you become who you admire, and that's really true, I suppose. That was the basis for the essay that got me in here, actually.

I seem to have made a good impression on the dean of students and the head of the psychology department. Someone said on Facebook that it's because I actually care about what I'm learning. I know it's beneficial to me to stand out in that regard, but I wish I didn't; I wish more people cared.

I miss Ava.
