It is a rare to have an unknown population mean and a known population variance
forming a hypothesis is when you come up with an educated guess.. what you think it may be . testing a hypothesis is when you're testing to see if someone else's guess is right.
examining/ experimenting/ testing/ verifying... it depends on the type of hypothesis to an extent I think.
A hypothesis is a suggestion of a way to explain something. If the hypothesis is tested and confirmed, it can advance to the status of theory. The conclusion of testing a hypothesis will be either that the hypothesis is confirmed, or it is not confirmed.
Rejecting a true null hypothesis.
You use a z test when you are testing a hypothesis that is using proportions You use a t test when you are testing a hypothesis that is using means
A statement made in advance that expresses the results that will be obtained from testing a hypothesis is a prediction. A hypothesis is supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
In Statistics, for making inferences or judgement from the data collected, hypothesis is laid, which is nothing but a statement made based on the sample, about the population of interest. After the experiment is complete, the values are compared with the table values, and inferences are made either by disproving the hypothesis, by accepting the null hypothesis and vice- versa It means to perform an experiment on your hypothesis (theory) to see if it is correct or not.

A Hypothesis is a statement that may or may not be true; in essence, a theory. Knowing that, testing a Hypothesis means to test a theory that was made about a certain event occurring or not occurring.
The purpose of controlling the environment when testing a hypothesis is ultimately to get a reliable result to the study.

an experiment
By testing.
Testing experimentally a hypothesis is the last step.
