Inverse transform sampling question

(b) Using the relation just above between the logistic and uniform distributions, as-
sume that we have sampled, using the inversion method, a number N (very high)
of samples (x;)i=1,,N of the logistic distribution Logistic (0, 1).
State 3 different methods that could be used with the samples (x;); (possibly also with
the knowledge of F, F-1, the density function and whatever else you find necessary)
to verify (graphically and/or with computable quantities) that the samples (x;); do
indeed come from the logistic distribution Logistic (0,1).
For each method give a very small explanation (no more than 1 or 2 lines) of what
you are supposed to observe/find with the method you state that confirms that the
samples (x;); do indeed come from the logistic distribution Logistic (0,1).
