A theory. If it has been proven and is replicatable, it is a fact.

What do you call the statement that determines if the null hypothesis is rejected?
The hypothesis test.
What do call the sloping line of a triangle?
hypothesis
What do you call the process of rejecting null hypothesis?
The process is called hypothesis testing. If you are inquiring on how to prove or disprove a claim, search for the article on wikipedia.
Why do hypothesis need to be tested?
It is a simple question, but sometimes simple questions do not have simple answers. I have included two related links which I feel are very helpful. Don't be worried if you don't understand much of the math in the second link. You may find less mathematical explanations by searching the internet for "hypothesis testing" You asked this both in science and statistics. You know sometimes the same word can have two meanings. Hypothesis testing is one of them. I will explain why we must test hypotheses in science, and what it means to test them in statistics. In science, a hypothesis is a speculative idea or explanation of a phenomena. Evidence or data is collected in an unbiased manner as possible to either prove it or disprove it. But how much data or evidence do we need? Sometimes, our hypothesis becomes a theory, a reasonable explanation that seems to fit circumstances or events, that will help us make decisions. As more observations seem to support the theory, we consider it to be valid or truthful theory. Many, for example, consider global warming to be a valid theory. Now, for the usage in statistics. Hypothesis testing is a statistical method. Hypothesis testing tells me if I have sufficient data to draw a conclusion, given a certain level of significance. I will give you an example: I have gathered some data and calculated a statistics on smoking. I found in my sample more women smoked than men. But, of course I didn't survey everyone, so there is a chance that my data has error in it, and perhaps I really don't have the necessary support to make this statement about everyone (the general population). So, I use a statistical test, with one hypothesis contrary to what my data suggests, that women and men smoke equally, which we call the null hypothesis. Now, I have a second hypotheis which we call the alternative hypothesis, which is that women smoke more than men. To complete the test, I need to include an "alpha factor" or the level of significance. I can with this factor, make it very easy to disprove the null hypothesis or very difficult. I generally use this factor to make the criteria for choosing between two hypothesis consistent.
What is the difference between the power lines phase 1 level 6 and the power lines 2 phase 7?
Helpful. What you call "power lines 1 level 6", it has to make 10 and there are six powercells. What you call "power lines 2 level 7" is has to make 21 and there are more than six which is 9 powerce.
What do you call the statement that determines if the null hypothesis is rejected?
The hypothesis test.
What do you call an untested conclusion?
hypothesis
what do you call a science statement?
hypothesis
What is it call when you test your hypothesis?
experiment
What do you call the prediction to a problem that will be tested?
The "hypothesis"
What do you call an experiment not being tested?
a hypothesis
What do call the sloping line of a triangle?
hypothesis
What do you call someone who has gained a scholarship?
You call that person a scholar.
What do scientists call theories that explain all the evidence?
I think they call it ''HYPOTHESIS''
Why can a supported hypothesis not be called a theory?
A hypothesis cannot be call a theory because,it has not supported a prediction even in the face of several experiment.
Why do scientists call evolution a theory?
Because it cannot be proven or replicated.AnswerIn science, a hypothesis is a good idea, a possible explanation, which might be right and might be wrong. Hypotheses can be refuted by experimentation. If the expectation from the hypothesis is not met by the outcome of experiment, the hypothesis is refuted. The longer a hypothesis survives unrefuted the more confidence we have in it. Evidence can support a hypothesis. The more evidence one has in support of a hypothesis, the more grows our confidence in it. Within the philosophy of science of Karl Popper, a hypothesis cannot be proven, but one can have a mighty amount of confidence in one, proportional to the amount of evidence in support of it. Unrefuted and with backing evidence, a hypothesis is promoted to a theory! A theory is better than a hypothesis. Evolution has much evidence from comparative genetics, comparative morphology and the fossil record. Evolution was once a hypothesis. Darwin collected a large mass of evidence for On the Origin of Species and now we have evidence from Mendelian genetics and comparative genetics, which Darwin knew nothing of. We now have a greater fossil record than Darwin did. There is far more evidence these days (for what is now called Neodarwinism or the Modern Synthesis- the combination of genetics and Darwin's basic 1859 ideas) than there was in Darwin's time. Evolution now has so much evidence that it is best to call it a theory, rather than a hypothesis. Yes, theories are unproven, but in Popperian philosophy of science they cannot be proven. Theories survive refutation and have much evidence and explain a lot. Biology regards evolution as its baseline, its most important idea ever. It might only be a theory of which we can only be 99% confident, but it explains everything so well that most biologists should better call it a fact rather than a theory. Evolution is such a good theory that its pedantic differentiation from 'fact' is entirely unnecessary.
