If your test statistic is symmetrically distributed, you can select one of three alternative hypotheses. Two of these correspond to one-tailed tests and one corresponds to a two-tailed test.However, the p-value presented is (almost always) for a two-tailed test.his means that .05 is in one tail of the distribution of your test statistic. When using a one-tailed test, you are testing for the possibility of the relationship in one direction and completely disregarding the possibility of a relationship in the other direction.
Different parts of the brain control different human behaviors. 1. The Amygdala is an almond-shaped set of neurons located deep within the brain's medial temporal lobe. It plays a key role in processing emotions, and is linked to both fear and pleasure in humans and other animals.
Because of a less developed brain, animals have not been able to originate words or a language to express their feeling. Hence they canât talk like we do. It is a well-established fact that the animals too feel happiness, sorrow, fear, love, affection, hostility, hunger, thirst or protection needs etc. as human do.
