Hello dear Henser,

You seem to be asking a homework question, which you will not get answers
for here.
In short, have a look at:
?read.table
For reading the data.  And:
?mean
For the mean...

And go read through an introductory book on R.
There is a long list here:
http://www.r-project.org/doc/bib/R-books.html
And another list here: (this link includes only freely available books)

Cheers,
Tal
