Could it be that there's an issue with the ordering of the indexes for data? Judging from m=data//Length, data seems to be a $n\times 2$ array, but later you're accessing it with i as first index, with $i\in\{1,2\}$

Actually you should not be using Block here because the results will be messed up if data contains \[Mu] (or even i). Generally, stick to Module unless you know that you need Block. If you use Module, you will need separate mu and mu0 due to Module's symbol renaming.

Re your update: Once you've calculated $\mu$ and $\sigma$ and stored them into mu0 and sigma0, use With to inject them. With[{mu = mu0, sigma = sigma0}, Function[..., ... mu ... sigma ...]]. In fact you can even just use mu and sigma throughout (not mu0) and do With[{mu=mu, sigma=sigma}, ...]. If this is confusing to you, stick to separate names (mu and mu0).

Why do you keep using Return and extra semicolons when they are not necessary (even even hurt performance)? Use Block[{}, ...; result], not Block[{}, ...; x = result; Return[x];].
