I'm very good at math, at least in my class.

Re: Brony Thread
Is that stats 0.o I got an A in stats and I aint entirely sure about how to go about that. I know standard deviation and I know mean but confidence level I have never encountered. But apparently its a plug the values into an equation thing so I'll try and get back to you momentarily.
so apparently 15 +/- 2.045(value obtained from a table) (4/root 30 )
just plugging your formula together my friend but I have never run into that one

Re: Brony Thread
So why are we talking about maths in a pony thread?

Nope, it's Vinyl Scrath's day. The awesomest (not a word) pony yet.

Re: Brony Thread
So your answer would be the following
15 +/- 2.045(4/root30)
95% confident the value lies between. 16.5 (3 sig fig) and and 13.5
Hope that helps!

Re: Brony Thread
Awesome! +1, all the way!
If you don't mind my asking how do you arrive at that solution?
And here's my other problem. Basically the same thing...
Calculate the 95% confidence level for the following mean:
Mean = 15; Standard deviation = 4; N = 2500

Re: Brony Thread
I know that there are 6 main ponies. Does that count as math?

Re: Brony Thread
Omnipresent meaning everywhere at once basically (omni= all present = well... present xD) and I thought you have always had more posts than me....
@spur 6 MANE ponies
@ wade this one I am not certain about but this SHOULD be right...
15+/- 1.960(4/50) 50 being the square root of 2500 and 1.960 being from a table...
giving you... 15.16 or 15.2 to 3 sig fig. and 14.84 or 14.8 lol

You've had more posts than me for a long time.

Re: Brony Thread
Okay and how you arrive at the solution is using a formula which goes as follows: Mean +/- t*(standard deviation/ square root of N)
Mean which you are given
+/- (meaning that one of the boundaries will be adding and the other you will take away to find.)
t* which is a value which must be taken from a table which is gathered by looking on a table you should have since you have been asked to this
find the column with your desired confidence level and the row with N-1 which is your degrees of freedom apparently. read off the value in that cell.
your standard deviation which you are given and the number of samples you have which only needs to be square rooted before being used in the forumla

Okay, I shall try to stop derailing the pony thread with mathematics now
Also spur I have been quiet recently haha not much to say... which is rare for me.

Great stuff, dan. You really saved my *** on this one.
If you ever need anything, do not hesitate to ask.

Re: Brony Thread
Well there is this Body I've been hiding under the house but if you have space...
Kidding but thanks glad I could be of help. if you ever need help again feel free to ask. although maybe make a thread. I think I am disrupting the equestrian vibe for you guys xD
