Significance Definition and 264 Threads

Let N be the number of flips of a coin up to an including the first flip of heads. Develope a significance test for N at the alpha=0.1 to test the hypothesis H that the coin is fair. Can someone please help me with this statistics problem? I have no clue how to start it. Thank you :smile:

Having laid down the foundations for a theory of causal significance in chapter 9, we can begin to investigate applications of its principles in order to get a firmer grasp on the concepts and derive some theoretical results. Rosenberg demonstrates applications of the theory of causal...

Our considerations of the problems of consciousness thus far have repeatedly brought us to questions about causation. In chapter 8, we saw arguments that we should be realists about causal connections. Given that causal constraint is a real feature of the world, what can we say about it, and...

What is the physical significance of phase or phase difference

Hi...I've been scratching my head for this one: If f(x) and g(x) are realvalued functions integrable over an interval (a,b) then prove that |\int_{a}^{b} f(x)g(x)dx| \leq \sqrt{\int_{a}^{b}(f(x))^2dx \int_{a}^{b}(g(x))^2dx} I actually don't want the proof of this inequality...I already...

I am intriqued by a recent series of three papers on black holes: http://www.arxiv.org/abs/gr-qc/0411060 Title: The river model of black holes Authors: Andrew J. S. Hamilton, Jason P. Lisle (JILA, U. Colorado) http://www.arxiv.org/abs/gr-qc/0411061 Title: Inside charged black holes I...

My teacher, Sai Baba, who has over 100 million followers .. says that 9 signifies God, because whether multiplied or divided the answer digits always add up to 9. Changelessness is an attribute of God. http://www.sathyasai.org I believe that if you ask Baba or your favorite form of GOD...

As i understand spin of a photon can be -1 or +1. In a classical view we can say that one is spinning right and other to the left ? What would be the difference between light with all photons -1 and light with all photons 1 ? PS: Can be spin of a photon also 0 ?

The genesis of this thread is Why this is still Amerikkka, where there was a lively discussion of the extent to which many sub-Saharan countries are still economically undeveloped as a result of the genes of their inhabitants, the extent to which those genes are responsible for agriculture and...

While I understand the use of the Lagrangian in Hamilton's principle, I have the gut feeling that there is more to it than meets the eye. For instance, while the hamiltonian is conceptually easy to understand and even I could have thought about it, the Lagrangian is something else. I would...

How has the near equality of the Sun's and Moon's apparent size (as seen from Earth) affected our planetary history (vs transient phenomena like eclipses)?

there is much written and on the web about ZPE it is an ofshoot of real physics ,with as far as i know no proof. my question is why anyone gives it creedence. why has it become so important? must go my overunity teamaker is boiling best wishes

i wonder... what is the significance of a hero? in evolutionary thinking the mindset that would create a hero would be a defect that would elliminate itself. or is there something more? is there truly a lasting change that one can leave besides their contribution to the gene pool, or is it...

Consider this case: A ball is allowed to fall freely with a constant acceleration of 10 m/s^2. What will its speed be after traveling a distance of 10 m? We get that: v[initial] = 0 m/s d = -5 m (downward direction is taken as negative) a = -10 m/s^2 To find v[final], we will use the...
