Hi, I need help with this question
What is the probability that a random variable V which is uniformly
distributed on the interval [0; 1] lies within 2 standard deviation units of its mean?
I was told to standardise this variable by taking away its mean which is and dividing by it's standard deviation which is
With that I end up with z-values -2 and 2
Is it correct to use a normal here?
and (see http://en.wikipedia.org/wiki/Uniform...n_(continuous)). It is simple to calculate .
