Unformatted text preview: Exercise 26 Answers Philosophy 102 (Maher) Spring 2009 1. (a) p ( E | H 2 ) > p ( E | H 1 ) so, by the law of likelihood, E favors H 2 over H 1 . (b) p ( H 2 | E ) /p ( H 1 | E ) = 1 > 2 / 3 = p ( H 2 ) /p ( H 1 ) so, by the definition of favoring, E favors H 2 over H 1 . (c) p ( H 1 | E ) /p ( H 2 | E ) = 5 / 4 = p ( H 1 ) /p ( H 2 ) so, by the definition of favoring, E doesnt favor either hypothesis. (d) p ( E | H 1 ) > p ( E | H 2 ) so, by the law of likelihood, E favors H 1 over H 2 . (e) p ( E | H 1 ) = 0 . 2 > 1 / 6 = p ( E | H 2 ) so, by the law of likelihood, E favors H 1 over H 2 . (f) p ( E | H 1 ) = 1 = p ( E | H 2 ) so, by the law of likelihood, E doesnt favor either hypothesis. (g) p ( E | H 1 ) = 1 > . 6 = p ( E | H 2 ) so, by the law of likelihood, E favors H 1 over H 2 . 2. (a) If N then species are formed by accumulating individual differences. This will produce different varieties that gradually diverge until they are so different we count them as different species. But since the divergence is gradual, there will always be groups atdifferent species....
