HELP!!!!
Ok all you math geeks, I need a little help. I have an extra credit question for homework and I'm having trouble with it.
A fair die is tossed. If it turns up 5 or 6, you win $2. Otherwise, you win nothing. Let x be the amount you win in one play of the game and X (x-bar) the average you win in two plays of the game. Give the sampling distribution of the sample mean, X (x-bar). I know this is a probability distrubution and it's early stat stuff, but I've forgotten it (it's been 10 years, sheesh, gimme a break) and now I'm stuggling with this one problem! Please help! ~stephen |
