No idea what else To put from the distribution with Let X, X,....,x,, be a random sample of size probability density function fx(x) = fx(x;e) - (0-1)2 bar x>1. >1. To answer this question, enter you answer as a formula. In addition to the usual guidelines, two more instructions for this problem only : write ) as single variable p and as m. and these can be used as inuts of functions as usual variables e.g log(P), m^2, ex etc....
