Is the given answer to the problem correct?

Now, let us differentiate with respect to 0 and equate it to zero. d log L(0) n =0-n> > (x; - 0) (-1) =0 do 1=0 n> > (xi - 0) =0 1=0 E(x - 0) =0 I'M= ! Ti - ne = 0 Ti = no I'M: I'M D; = 0 0= I(a) Consider the shifted exponential distribution with probability density function given by fx (x; 0 ) = le-1 (x-0), x20. When ( = 0, this density reduces to the usual exponential distribution. When ( > 0, there is only positive probability to the right of 0. Find the maximum likelihood estimator of 1 and 0, based on a random sample of size n
