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.
