Let \(\displaystyle X_1...X_5 \) be ordered statistic, x between -inf and inf

Find the likelihood ratio for testing the hypothesis \(\displaystyle H_0: \theta=\theta_0 \) against\(\displaystyle H_a : \theta not = \theta_0 \)

likelihood function= \(\displaystyle \Pi \frac {1}{2} \exp {-|x-\theta|} \)

Not really sure how to continue?

Any help will be appreciated

Thanks in advance
