Homework Help: Statistics

Posted by Sam on Sunday, November 1, 2009 at 9:30pm.

Among employed women, 25% have never been married. Select 10 employed women at random. What is the mean number of women in such a sample who have never been married? What is the standard deviation?

I think the mean would be 2.5, but I'm not sure about the standard deviation.
