Sorry it's statistics.. Actually I'm looking for the answer for a friend of mine. She said she has tried for days. but can't solve this. Now she has only today left for this question.. (for an assignment or something) Sorry I don't think I can provide pictures for "What have you tried?" Anyway, here is the full paper; the 5th question is what she wants. http://i.imgur.com/QnBxP5g.jpg Last edited by skipjack; August 22nd, 2016 at 02:04 PM.
