Find Confidence Interval w/o Formula: Uniform Distribution

[lildrea88]

i am given a set of numbers. I have already found the mean, standard deviation, etc.
i am now asked to find the confidence interval. but was not given a formula in order to compute this. does anyone know one?

the practical example here shows how to get it.

What confidence interval are you looking at?

 

[cloud360]

write it in terms of the mean (that u shaped thing in the normalization eqation), choose the correct value of Z for the confidence interval they give.

95% confidence interval ==> z=1.96 (for 2 tails)

98% confidence is something like , i don't know off by heart, check the normal table

So you want P(-1.96<Z<1.96) and you know that Z = (X-μ)/(σ/√n)

so in all you want the CI to be

P(-1.96<(X-μ)/(σ/√n)<1.96)

i need a confidence interval for the uniform and bernoulli distribution...sorry i should have said that before

I can't really recall if it is the same for those distribution, but you can approximate them to a normal distribution.
