Think this through:
First, I assume by "r" you mean correlation coefficient. Take a look in your text book and it should tell you what the possible range of values for r is.
You have a mean that's a negative number. Is that a problem, or not?
You have a standard deviation s that's a positive number - do you see any problems with that?
Now post back and tell us what you think the right answer is.
