Basically, this table contains results of a study comparing Chemo with Surgery in treating Cancer of the Larynx. C = Cancer Controlled, NC = Non-Cancer Controlled. I'm supposed to use Fishers Exact Test and interpret results.
Using the hypergeometric distribution,
P(n11 = 21) = (23 C 21) * (18 C 15) / (41 C 36) = .275
I'm not sure how to interpret that result. I'm also supposed to find a one-sided P-value (manually) too, which I'm also unsure.
