# Math Help - prove asymptotic distribution

1. ## prove asymptotic distribution

$I^{-\frac{1}{2}} U \approx N(0,1)$

and

$I^{\frac{1}{2}}(\widetilde{\theta}-\theta)\approx N(0,1)$

I is fisher information, $\widetilde{\theta}$ is mle

how to prove these two arguments

2. What's I and theta?
And is there a question here?
