    I've only ever done chi square calculations in Excel. Their data analysis plug-in tool gives a pretty good summary of the results, though.

    We don't do homework for students here. But tell us what you have done, and where you've gotten stuck, then maybe someone can point you in the right direction.

    Your post is basically "Do my homework for me." That's bad form.

    I have a home work question:

    If 750mL of Vodka costs $13.42, and 375ml costs $8.23, how many ex girlfriends will I call before 2 am?

    It depends.
    How many of them are likely to lend you the money for the vodka?

    Well..fortunately you don't need ex-girlfriends with money to buy you vodka, when little old ladies call you to mow their lawn, and pay you with beer. Bless Marina's heart. She sends her love.
