Answer:
d. Internal coherence demonstrates the rational relationship between parts of a hypothesis.
Explanation:
The<u> statement "d" best describes the internal coherence of a hypothesis </u>because if the different parts of a hypothesis aren't coherent with each other, aren't related, there's no internal coherence in the first place. All the different parts have to have a rational relationship, have to be rational with each other.
At the level of 0.05% significance we can not reject the psychologist's claim. His claim is supported.
Explanation:
When a researcher undertakes a project to do research firstly he takes some random samples. Sample is definite a small group of numbers assume to represent the whole population. Suppose a researcher wants to do research on married couples to find the trend of divorce among them. For that reason he will randomly choose some of the couples and will draw conclusions that inter personal communication reduce the chances of divorce.
Now to establish this experiment as a fact he needs to go through a test of level of significance. Where he will get the result that his statement is established or rejected.
A theory is a conclusion that is drawn from observations and experiments, but a law provides an explanation. this is the answer strictly because within science everything can be proven wrong nothing is set in stone
