I am given a Probability Mass Function for a discrete random variable. From the PMF I computed the Expected Value $E[X]$, the Variance $V[X]$ and the Standard Deviation $S[X]$.
Here is an example (the dotted grey lines are $E[X] - S[X]$ and $E[X] + S[X]$, respectively). We could think about it as a loaded dice with values 0 to 5.
At this point I have some doubts about how to construct a 99% confidence interval for $E[X]$. Can someone help?

whose average is such that the chance of (0,a) is 0.5% and the chance of (b, 5.5) is 0.5%. This will give you a 99% confidence interval, albeit one with decimals in it $\endgroup$
