Tuesday night's HW:

"A poker-dealing machine is supposed to deal cards at random, as if from an infinite deck.  In a test you counted 1600 cards and observed the following:

Spades 404
Hearts 420
Diamonds 400
Clubs 376

Are these discrepancies just caused by random chance, or is this machine suspicious?  Use Chi square test to determine.
