A hypothetical experiment, exposing two strains of cells (n = 20 of each strain) to viral infection and assessing cell death and survival. The hypothesis of equal deaths is suggested in the upper right panel. Below, we illustrate the actual result and two possibilities that are less likely than the observed result, if there were in fact no difference in death rates between the groups.
