I found something a little different:
> median(nb10[,1])
[1] 404
> mean(nb10[,1])
[1] 404.59
compare them....
They are different. Your sample is not perfectly symmetrical (50% above,
50% below) about the mean (ie. the third standardized moment (skewness) is
not zero). This is really not a question about R, and this is not a place
to get answers for homework.
Good luck with your studies.
