Fisher's Exact Test.

• Fisher's exact test is " exact " because it guarantees the α rate, regardless of the sample size • Example, food additive and 14 mice Tumor None Total Old 4 3 7 New 2 5 7 Total 6 8 • p 1 = prob of a tumor for the old additive • p 1 = prob of a tumor for the new additive • H 0 : p 1 = p 1 = p • Can't use Z or χ 2 because SS is small • Don't have a specific value for p
