since when chicks know statistics..i guess they can stick to the basics. Try non irreduceable stochastic optimal control and brownian motion problems

@Sam10947 I loved studying Markov processes. Brownian motion, as I am sure you are aware of, is just a strong Markov process. Now the interesting thing is that you are apparently using the Brownian motion to describe something. So, are you using the nonirreduceable stochasitc optimal control to model behavior in nature, machines, or in finances? This is a very interesting little project. I would love to see what problems you are specifically talking about if you can handle a CHICK showing you up

why do we reject the null hypothesis when the p value is less than the level of significance?

could you please give me an english explaination to why its rejected?

[tcreelmuw]

@IbanezV70CE The significance level is our rejection region. It is the maximum area that we require to reject the null. The P-value is the area of our data (the test statistic). It is our evidence against the null. If the P-value is inside the rejection region, we have the evidence to reject. If any of the area of the P-value is outside the rejection region, we don't have enough evidence.

Do smaller alpha's indicate greater degrees of significance?

[tcreelmuw]

@S4disticJ0k3r Yes it does.

@Catheranne You need to look up the value in the z-table. Go down to 2, then go across to .05, which shows you .4798. You then need to subtract it from 0.50 (because each side is 50% of probabilities), so 0.50 - 0.4798 = 0.0202.

you made things much clearer for me on this, all though I did have to watch the video about 10 times,( rewinding numerous more) because I was trying to figure out numbers....and it doesn't help that you're very beautiful. I'm still having trouble figuring out the sig. diff. when 'mu' and "std. dev." is not known..

[POLAK1Nysa]

@tcreelmuw Can I calculate the P value this way for a T-test?

Right after she says "hi", I was thinking bye, get back to the kitchen x DDD

[rac2450]

@hohohee1 hahahahahah this is so much typical and can apply to so many people...good you're saying it out loud man!

[Sam10947]

@tcreelmuw

i'm just grown up man with warrior heart and a kid attitude, hence the joke

[Sam10947]

@tcreelmuw

A chick would show me up if she comes up with Lemme or theorems or some sort of algorithm to solve exponentially complex divergent problems, or solve the next challenges, like the control of a fusion plasma profile. so what is ur point ? am i sensing the fact that u r trying to portray ur offense or is it the fact that u didn't construe and distinguish a sensical observation from sarcasm

I want this video on my T707 phone.

This is a very "hysterical" video. =p
