Null hypothesis of a one-way ANOVA is that the means are equal. Alternate hypothesis a one-way ANOVA is that at least one of the means are different.
Yes, usually.
YES!
The process is called hypothesis testing. If you are inquiring on how to prove or disprove a claim, search for the article on wikipedia.
Neither. It is a hypothesis which may be true until proved or proved to be false.
A different claim proposing another hypothesis
No, it never does!
with the alternative hypothesis the reasearcher is predicting

When writing hypotheses the null hypothesis is generally the hypothesis stating that there will be no significant difference between the variables you are testing. An alternate hypothesis would be a hypothesis suggesting that the results will be anything other than not significant. For example if you were testing three concentrations (low, medium, and high) of a type of medication on cancer cells, then one example of an alternate hypothesis would be that the medium concentration would decrease the number of viable cancer cells.
You test a hypothesis after you form it. But lets go over the scientific method anyway. You start with a situation, then you come up with a question, then a hypothesis: there are two kinds of hypothesis, null and alternate, null means that the results dictate that the treatment shows no Significance, where alternate shows that the groups have difference, which is significance. You test the hypothesis in an experiment, and there are many different tests that you can apply to the DATA you collect.
The null hypothesis makes a claim about the absence of an effect or relationship in the population. It assumes that any observed differences or relationships in the data are due to chance. Researchers aim to reject the null hypothesis in favor of an alternative hypothesis to support their research hypothesis.
It shouldn't be always disprovable, because your hypothesis should be a educated guess, based on facts an other info.So....A HYPOTHESIS SHOULDN'T ALWAYS BE DISPROVABLE.
Yes; the null hypothesis, H0, always includes an equality. The alternative hypothesis, H1, is >, <, or does not equal.
