observation and experimentation

Most scientific hypothesis are tested using the scientific method by asking questions and doing experiments.
a hypothesis is a statement to a certain opinion whereas a problem is an issue between 1 or more people the most significant difference between problem and hypotheses is a hypotheses can be tested but a problem can not ,as problem is just question.a question can not be tested unless it is not transferred in to hypotheses
Once a hypothesis is tested and the results are replicated through further testing, the hypothesis can be said to be proven or disproven. Even if a hypothesis is disproven, the results can be very important and should not be considered a failure under most circumstances.
The Null Hypothesis. May be referred to as (H0). It is a statistical test and tricky in that this Null hypothesis can never be tested, so is tested in conjunction with some other hypothesis in such a way as the testing procedure, measurements made, will be done in a way as to show which hypothesis is more likely. An example is given in Wikipedia regarding the tossing of a coin is worth viewing. Null Hypothesis : we have a normal coin Alternative Hypothesis one: we have a double headed coin alternative Hypothesis two: Some unknown influence on an not normal coin if a coin is tossed many times, say 100, and comes up heads each time the Null hypothesis is least likely of the three and REJECTED in favour of one of the other alternatives. if the coin flips over and over and over easily but always lands heads up, most likely hypothesis two is correct and the Null Hypothesis REJECTED. if the coin acts real strange by not going end over end and immediately falls very quickly down to land one particular side up hypothesis three is more likely and the Null Hypothesis REJECTED. if the coin acts normally going end over end and lands about as many times heads as it does tails the Null Hypothesis is RETAINED as most likely. The Null Hypothesis is either retained [kept as most likely true] or it is rejected in favour of the alternative. so it can be seen choosing which alternative to test against is always best and the simplest is generally the one to look at. refer also Ocams Razor.
Yes, if there is enough evidence and data to show that the hypothesis is most likely true.

To answer a specific question, scientist form a hypothesis. If the hypothesis cannot be testable or answered, they'll give you a prediction of what will most likely happen from the results of the hypothesis.
Scientific hypotheses are most often tested by conducting experiments, collecting data, and analyzing results. This process involves comparing the outcomes of experiments with the predictions made by the hypothesis to determine its validity.
If I understand the question correctly, ALL of them can change...In principal. That is, a scientific law could be proved false, though it is the most tested of theories and least likely to be changed. That is the beauty of science. Nothing is beyond question. Let's review a layman definition of these terms: Hypothesis --> Reasonable, but not fully tested, guess to answer a question. Theory --> A fully tested hypothesis that's been checked by others to a question. Law --> A theory that's been around a while that no one can find fault with. Experiment --> Logical process to test a hypothesis...They are changed ALL the time.

A hypothesis is formed from a question. this question is most likely to get scientists debating on weather it is true or not, and this is where the hypothesis comes from. a hypothosis can either be true or false. you will use a hypothesis in science for your G.C.S.E and sometimes in mathematics.
Have you heard the word "theory" used in a different way by non scientists in everyday conversation? How is this use of the word different from a scientific theory?
scientific advances in many fields of Biology, along with geology and physics, have confirmed and expanded most of Darwin's hypotheses
The theory of evolution by natural selection has been one of the most extensively tested theories in science. It has been supported by a vast array of evidence from multiple scientific disciplines, including paleontology, genetics, and comparative anatomy. Additionally, the theory has been able to make accurate predictions about the natural world, further confirming its validity.
Theories are ideas accepted as most likely true. Theories are basically hypotheses which have been tested many times by many people and are found to be true.
