Experiments were designed to determine if males use color cues in their mating decision and if their behavior could explain the significance of the ontogenetic color change from fifth instars to adults. The p-value is the level of marginal significance within a statistical hypothesis test representing the probability of the occurrence of a given event. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Our task now is to reframe the hypothesis is a form that is consistent with the available information.
