Okay, I have a dataset to work with for an assignment in a graduate class I am taking. I don't understand what this question is asking me, exactly, and it's driving me nuts:

"Conduct a one-sample t-test in which you determine whether the mean of the difference in every TP concentration upstream minus the corresponding downstream TP concentration is equal to 0 or significantly different than 0. State your null hypothesis and test conclusion."

How do I do this in R? We never did this in class. I'm not wanting you to do my homework either, I'm so new to R and I don't know how to start doing anything in it. It makes me anxious.

    Have you asked the professor for clarification? That would be my go-to if I didn't understand my homework. – Rich Scriven Oct 09 '17 at 18:58

    `?t.test` is the help page for t tests. There are examples at the bottom. – Gregor Thomas Oct 09 '17 at 19:06

    As @RichScriven commented, the best course of action is asking your professor. However, if you wish help here in SO, you can post a [reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example#5963610) – csgroen Oct 09 '17 at 20:08
  • I eventually worked through this on my own, but thank you for the responses. A lot of the terminology associated with R and comp. sci-related things makes my head spin. It's geting easier with time, though. – hmnoidk Oct 10 '17 at 19:48
