Dear Sir/Madam,

While reading R-intro document (found here
http://cran.r-project.org/doc/manuals/R-intro.pdf) on the page 37, I have
found such text

*which does indicate a significant difference, assuming normality*

referenced to t-test for equality of two means (unpaired t-test).

Could, you, please, comment, what type of "normality" is meant in the text?

Thank you in advance,
Aleksandrs Gehsbargs
