## Rayleigh distribution exact test.

Suppose the following data is a random sample from a rayleigh distribution with unknown parameter $\alpha$
3.45 5.83 1.41 2.71 3.84 1.18 8.08 3.43
Test if the mean of the Rayleigh distribution from which the data comes exceeds six. Use an exact test here.

What test would they mean by an exact test here?
