Question

In games of poker, it has been hypothesized that a companion coughs or scratches their nose whenever an opponent has a better hand, at which point the customer folds thereby minimizing losses. A casino observes 75 hands of poker that the customer has played:

	Customer Folds	Customer Doesn't Fold
Coughs	15	6
Scratches	6	4
No Signal	11	11

Test the null hypothesis that the probability of folding is independent of the probability of a cough and the probability of scratching versus the alternative hypothesis that they are not independent. State your conclusion at the a = 0.01 level and the p-value of this test.
