WebbW. D. Hamilton proposed the theory in an article titled "Geometry for the Selfish Herd". To date, this article has been cited in over 2000 sources. To illustrate his theory, Hamilton asked readers to imagine a circular lily pond which sheltered a population of frogs and a water snake. Upon seeing the water snake, the frogs scatter to the rim of the pond, and … WebbFor example: the hypothesis that a coin is fair, e.g. the probability of throwing heads is equal to 1 2, is a simple hypothesis, because the parameter of the binomial distribution, p, is specified to be 1 2. Another example is of a simple hypothesis is ”Our medicine does not have an effect on the blood pressure.” We probably
