Testing Hypothesis in R. Need help!

The Cookbook for R is a good first stop for learning how to do common tasks in R. There's a chapter for statistical analysis that includes hypothesis testing.

If you're doing this for a class, consider asking your instructor or the teaching assistants for help. They might enjoy the company during office hours. :grin:

As for your problem, there's not much to go on. What are your ideas of how to approach it? Have you run into any specific problems or fears? We are more inclined towards helping you with specific coding problems rather than doing your work for you.

If you want code help, could you please write up a self-contained REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help. Even just the data and your first attempt code would be fine.

If you've never heard of a reprex before, you might want to start by reading this FAQ:
