So, I need to check its means, that's why I have following questions:
- The easiest way to do it - is to use Mann-Whitney criteria?
- How to check, is it really exponential distribution? Kolmogorov-Smirnov? But it suits only for standard distr?
- And is it possible to use CLT for comparison of means: to generate a lot of means using bootstrap from two distr. Accordingly to CLT, means' distributions have to be normal and it becomes possible to use Students criterias. (Presuming, that it is a rather silly question...)
