Why is hypothesis could be rejected?
To reject null hypothesis, because there is a very low probability (below the significance level) that the observed values would have been observed if the hypothesis were true.
How can a scientific hypothesis be used to answer a specific question an observed phenomenon?

What is Hypothesis Testing of p-value?
The probability of the observed value or something more extreme under the assumption that the null hypothesis is true. That is, the probability of standard scores at least as extreme as the observed test statistic.
How can a scientific hypothesis be used to answer a specific question about an observation phenomenon?
A hypothesis can suggest an explanation for an observed phenomenon that can later be tested through experimentation
What do scientists use to answer questions?
The scientific process. 1. Observe 2. Create a hypothesis to explain what you observed 3. Experiment to test your hypothesis
What is example of a hypothesis?

Does a scientific hypothesis describe an observed pattern in nature without attempting to explain it?
False
What is an exlpanation that answers a scientific question and can be tested called?
A hypothesis. It is a possible explanation for an observed characteristic or phenomenon.A hypothesis usually becomes known as a theory when experimentation validates part of all of it.
