help with rstudio

by

I need help with Rstudio, it’s a homework assignment due tommorow, I understand how to do problem 2, not problem 1, and 3-5.I have provided an example of how I’m being required to do it and the homework. The teacher wants me to do the work on Rstudio, then copy and paste it to word along with the image of the graph. I just need help with 4 problems.
