Suppose I have a set of datas 8...20, with mean 10 and lambda 1/10=0.1 . I want to make a parametric bootstrap, supousing my datas come from an exponential distribution.

So now I may construct my random samples from an exponential distribution with lambda=0.1 . My problem is I do not know from where those random number come.

Do I have to construct my resamples from random numbers between the smallest and greatest values from my set of datas (8,20)? If not so, From random numbers between 0-1?

Any kind of help will be appreciated. Thanks in advance
