central limit theorem

[themathman]

having trouble doing the central limit theorem for a value that is inbetween 2 numbers.
i dont know what the mean value should be when doing my calculation for the v value. Im using -1 as the mean but that gives me a z value of 7.5 which i cant find on the table.

What have you been taught about the uniform distribution? What is the mean of Uniform(-1,1)?

 

[themathman]

I believe the mean is -1 while the standard deviance is 1

 

[Dr.Peterson]

No; why would the mean be at one extreme end of the range?

I'll ask again: what have you been taught about the uniform distribution? I'm expecting to see a definition, and maybe a couple formulas, such as one for the mean. If you haven't learned such a formula, it will be even more important to see what definition or other basics you know.

If you know nothing about it, you could start here: https://en.wikipedia.org/wiki/Uniform_distribution_(continuous)

By the way, I really don't want to know anything about "standard deviance". (You meant "deviation". Look it up.)
