Ok, I think I am starting to get into my statistics groove, but then I just got stumped on a few practice questions tonight. In my practice questions, they ask for the standard deviation. My calculator (and book) use n for "population SD" and n-1 for "sample SD"....so in the question, what would be my assumption if they don't specify population or sample? Their answer matches population, so I see what they did, but will the DSST exam specify which they want, use or is there a rule of thumb?

THANKS!!!
