"Is P value Type I error in hypothesis testing? I'm confused about the interpretation of P value in hypothesis testing. I know that we set significance level as 0.05 which is the threshold we set for this test so that it won't suffer from Type I error by 5%. And we are comparing P to significance level, does it mean P is the probability of making type I error based on the sample?"

now not quite. The p-value is calculated primarily based at the statistics we without a doubt found - it is our degree of how "uncommon" the records is, assuming that the null hypothesis is authentic (which typically corresponds to "nothing bizarre is occurring" or "the effect we're seeking to pick out isn't present" or some thing comparable).
the edge that we set, regularly written as alpha, wherein we decide that the p-price is satisfactorily "bizarre" to depend as proof in opposition to the null hypothesis, is then our chance of a type I errors - it's the possibility that, in a universe in which the null hypothesis is authentic, we get information so weird that we assume it is false.

New largest prime number discovery - what's all the fuss [duplicate]
So I've read about the latest largest prime number discovery (M74207281), but I find it hand to understand what's the big deal because using Euclid's proof of the infinitude of primes we can generate primes as large as we want.
I'll be happy to know what I'm missing

If you are already certain that a null hypothesis is false, then:
Significance testing provides no useful information since all it does is reject a null hypothesis.
Significance testing is informative because you still need to know whether an effect is significant even if you know the null hypothesis is false.
When a difference is significant you can draw a confident conclusion about the direction of the effect.

Why "bother" with a null hypothesis at all?
whenever i am seeking to get into data (once more), i am constantly lost at speculation trying out.
My simple question is - why can we form a null hypothesis as a negation of what we need to show within the first region, and most effective then can we show or disprove the null speculation?
Why do we do it at all, in preference to just proving the authentic speculation?

Least squares regression analysis is a common method for modelling trip generation. What are the main assumptions of the least squares regression analysis in that context? Discuss with examples the consequences of violating two of these assumptions.

I have a question as follows:
Assuming the null hypothesis is true for all cases. If we perform multiple pairwise comparisons at the α = 0.05 level, what is the probability of making type I error with AT LEAST ONE of the tests?
The correct answer is greater than 0.05, and I don't know why. Thanks in advance!
