Assume reality to be Fiction and literally everything imaginable will Comically prove that it has to be Fiction, especially Physics. Assume that reality is real and literally everything imaginable will make it appear real more and more until death wakes Fiction up to what Fiction is NOT. -- Really Reality
The Null Hypothesis is actually a term for a concept from statistics. Suppose, for example, that you're trying to test whether a new drug is effective or not. You can never be 100% sure that any effects you see on a limited test group of patients aren't due to chance, so what do you do? First, you decide just how sure you want to be that the effects are due to the drug. Is 95% sure ok? 99%? 90%? Whatever number you pick, that sets what is called a confidence limit on your results. The actual hypothesis you test statistically is "Drug X is effective". The null hypothesis is then "Drug X is not effective, or it is effective but not within the confidence limit decided upon." Attaining the required confidence level in the statistical test will require testing enough patients and being able to eliminate potential confounding factors. The process of testing a claim against a null hypothesis is a mathematically precise process. The end result of such a test is not certainty that what your results are telling you is true, but a precisely defined estimate of the probability that your conclusion is right or wrong.
By Whom "This Fiction by Whom" is the Supreme Comedy BECAUSE: YOU wrote it, but if you knew you wrote it then it would be utterly boring -- so to make this fiction entertaining you wrote it so you DON'T "remember" you wrote it. I should know because I AM you ... and the only thing that separates you from me is the thoughts that make up this "fiction by whoM" really
in many fields of "learning," science, the only way you can prove that something is true is by trying to prove it to be false: if it cannot be proven to be false then it is mostly likely true. reality/ fiction is exactly the same. the only difference: when you cannot prove that fiction is real then it becomes funny, the Supreme Comedy which is just a joke that makes a hallucination appear real. -- really
